Whenever I got to put a chicken back into the coop, it crouches low and smacks its feet on the ground, pulls its wings away and looks like it is about to fly. I noticed that whenever it just walks around normally its wings aren't even with its body. The stick out a bit. I felt under the wing and there doesn't seem to be anything there blocking it from going flat. It is a hen and an ISA Brown. What do I do? Should I be worried?
