Even before photoshop, people doctored images to get a laugh. What you see going on here is a delivery of poultry via horse power. Farmers were paid for their product by the wagonload. When a poultry dealer came to town and a long line of wagons would line up through main street, waiting their turn to be weighed. The gentleman that you see to the front of the photo is working the weights of the scale. Once a price was agreed upon, the crates of chickens would be put onto a freight train to take to processing near the city.
Recognize the breeds in this wagon? Barred feathers are found on a number of breeds, so they’re not necessarily Barred Rocks. Your guess is as good as mine. Chime in!
