My chickens are very friendly but all of a sudden when I walk up to them instead of running, they kind of coward(sp?) like a dog would when scared?? They drop down, and their wings look strange, the feathers go down and the bone goes up??? Is this normal? Does it mean anything? They have never been abused, and this behavior sure makes it easier to pick them up, but I wonder if something is wrong?? Has anyone ever seen or heard of this? Thank You!
