Help!! I went out to check on my chickens and on of my white leg horn hens was kinda roosten on the lip of then nesting box with her head down. I left her for a while...thinking maybe she is trying to lay. I went out about 1/2 hr later and she is still there...her comb is a funny color and she let me pick her up...which is wierd they usally run when you get to close. I picked her up and looked her over. I don't see anything. She just acts tired. what to do?/
