You could be right. Chickens are a lot smarter then people think. I trained mine to go into the coop with some fruit,vegetables or bread, when ever I want them to. My rooster will yell at the hens to get out of the coop, but they stay in the coop and eat all the goodies.I recently moved my birds around because I needed to empty a couple of the coops to move the older chicks into and the younger chicks into others that the older chicks were in and since moving many of the birds around to different coops and pens some want to either lay on the floor of their coop or on the ground. I think they are rebelling from being moved around.
