Fatty Liver Disease In Hens

WARNING: graphic photograph

A leading cause of death in caged laying hens is fatty liver disease. Also called FLHS or Fatty Liver Hemorrhagic Syndrome, it’s a disease in which the liver becomes compromised and eventually hemorrhages. Fat can no longer be processed and it is deposited on the organs and in the body cavity. Although the way that we care for our backyard hens seemingly has little in common with the industrial agriculture model of confinement in small cages and cheap food, our small flocks are also succumbing to fatty liver disease.

This is bad news, because the hens quickly loose vitality and die, but also good news, because it is entirely preventable.

FLHS is primarily caused by feeding too many carbohydrates, usually in the form of corn. This excess energy can’t be processed – basically the liver gives out trying. You might be feeding corn and say that you don’t have a problem. This is because unlike caged birds, most backyard hens are getting exercise and can burn some of the excess energy off. Also, caged birds succumb to FLHS because they are additionally stressed by confinement and high temperatures. However, even if kept in optimal conditions, as chickens age, they become more susceptible to the disease. I’ve seen and heard of many cases of fatty liver disease in backyard flocks.

When hens in commercial flocks die of fatty liver disease, it’s because the companies are cutting corners, feeding cheap grains, jamming the birds into cages, and not keeping the buildings clean and dry. Our chickens don’t live under those conditions, but they’re still getting FLHS. Why? The answer is that we are loving our hens to death.

Cracked corn is like candy to hens, and once they learn the sound of a can of corn rattling, they’ll come running. I know, because I’ve trained mine to come, and it’s hilarious and a lot of fun to watch (See video here.) But, corn, or the similar product of scratch grains, is nothing but empty calories. There’s no reason to feed it to your hens. Even “scratch grains” are not necessary to feed. I do have corn on hand for calling the hens back to the run, but I know the danger of feeding too much. Each hen gets less than a teaspoon as a treat and I don’t feed it on a daily basis.

I don’t because I’ve seen this:

Fatty liver disease in an older hen HenCam.com

 

You won’t find photos like this on veterinary sites or in research sponsored by the agriculture industry because this is what happens to an older hen with fatty liver disease. Even if you’re not feeding corn, this can happen. Sometimes it’s caused by bread and pasta. Whatever the excess carb, the liver is destroyed and the body cavity fills with thick fat. Often, when a chicken stands like a penguin and looks listless, the hen keeper thinks “egg bound.” That’s rarely the case. More often, it’s this.

But, it’s preventable! Don’t feed cracked corn on a daily basis, and if you do, offer it only as a training treat. Provide lots of interesting scraps from your kitchen, but make sure they’re vegetables and the like, not leftover breads and rice. Give your hens plenty of exercise and sunshine. Give them protection from extreme heat. There are so many diseases that we can’t prevent, but this one we can.

Good Day Sunshine

It’s time to wake up,

and face the sun.

I’ve been gardening on this property for a dozen years, and in that time I’ve had plenty of failures (for the life of me I can’t grow clematis!) but one success every summer has been sunflowers. Each year I plant more, and make sure that I have plenty of variety in color, size and height.

I purchase

 from my local plant nursery. Always read the labels – although the “pollen-free” varieties are tidier in cut flower arrangements, there’s nothing there for the bees.

It’s not only the flowers which are beloved here. I give the stalks to the goats, who think that the leaves are delicious and that the tough stems are good for head scratches.

Not, yet, boys. The sunflowers will stay in the garden awhile longer!

Why Outside Roosts

The other day, a small drama played itself out in the Little Barn’s pen. Veronica, the Marans hen, has gone broody. Midday, she took her bad-tempered and ruffled-feather self out of the nest to eat, drink, poop, dust bathe and preen. Broody hens look different – their feathers not only stick straight up, making them look larger and of a different shape, but they’ve often pulled some feathers out of their breast (the better to incubate those eggs that they deludedly believe that they have.) Different is not welcome in a flock. The other hens pecked at her head and chased her off.

In a free-range situation, Veronica could have put distance between herself and the flock and all would have calmed down. But my girls are in a fenced pen, safe from predators (and my garden safe from them.) If it was a bare enclosure, Veronica might have been cornered and harmed, so to prevent carnage, I provide several escape routes. The one that Veronica chose was the old ladder roost.

It’s under the

, which makes it bearable on a very hot day. Even better, for a bad-tempered broody, it’s in full view of everyone, but safe from them. In between preening, Veronica yattered away. But, up on the ladder, no one took notice of her. Not even the goats.

*Notice Veronica’s bare bottom. It’s nothing that I worry about. The skin color is normal, there’s no sign of damage from pecking. It’s not due to external parasites. My best layers often have bald spots. After last winter’s cold, snowy confinement, my flock is looking especially ragged. The girls won’t replace the worn out patches until after the molt late summer. They’re not up to beauty pageant standards, but that’s okay with all of us.

Outgrowing the Nest

It’s the last day of Phoebe Week, but I promise you that there will be more posts about the birds that have taken up residence on my front porch.

We’ve watched these slight little birds with the funny tufts of feathers on their heads,

build a stunningly beautiful nest and lay eggs the size of nickels.

Each day, in succession, another perfect egg was laid until there were five. They all hatched successfully.

I can’t say that the hatchlings were as pretty as the eggs, but no matter, even better, they show off their dinosaur ancestry. In five days they transformed from bare, wobbly, eyes-sealed-shut, helpless beings to these voracious and demanding creatures.:

Soon, they’ll leave the ledge on the porch.

Then these Eastern Phoebes will enter the wide world.

It’s not simply a bigger space, with food to find. It’s a community, and not just of other Phoebes. Birds are aware of and know other species of birds. They’re familiar with the squirrels and the chipmunks. The birds in my yard know my dogs and my goats. They know me. There’s a wonderful book,

, that gives insight into these communities of animals and how birds relate to them and to each other. Once you, the human, knows what to look for, a whole world of interactions opens up to view.

Over the last couple of weeks, watching the Phoebes, I realize that I have more questions than answers. When I do school visits, I tell the children to put on their science thinking hats, and they all pretend to tie a cap to their heads and then look at me with serious thinking faces. I then pose a question like, What do birds not have in their mouths? The answer is: teeth. Then the next question, How do they chew? The answer is: by swallowing rocks that go into the gizzard, which grinds food. As I watch the Phoebes, I put on my science thinking cap. The more that I watch the birds, the more I don’t know. Where do the parents sleep? If they reuse the nest, do they repair it for the next year. If so, how? If I remove the nest, will they rebuild in the same place? How far away do the Phoebes look for food? The survival rate for fledglings can’t be very high – if it were we’d be overrun with Phoebes (ten babies a year!) What’s the biggest risk? Do the ones that do live stay in the neighborhood? Do they return home after they migrate in the fall? Have you read a book that answers some of these questions? Do you have a natural history book to suggest for my summer reading list? It doesn’t have to be about birds. I recently read

by Katherine Courage. Now that’s an animal I’d like to get to know.

Feeding and Cleaning

It’s Phoebe Week, day Four!

It takes a lot of food to power the astoundingly fast growth of hatchlings. We see the Eastern Phoebe parents flying to the nest and then off again countless times during the day.

The babies are now so large, that even from a distance, I can see gaping mouths waiting for food.

What goes in must come out. The birds somehow have to keep that nest clean of feces. I hadn’t thought about how that was done, but then Steve caught the method on camera.

The baby bird turns it’s butt to the parent.

Out comes the manure,

and then flies off. I know where it’s being dropped – right on my porch five feet from the nest. It’s a mess. I’ll scrub it down when the birds fledge.

Once that’s done, there’s yet another mouth to feed.

The Phoebe parents have a demanding work schedule. But I have noticed them taking a moment for themselves.
