My five month old hen Mimi has been laying oddly on the floor of the coop sticking her legs out in front of her the past few days. I assumed she was trying to lay an egg because my other birds have started to lay and I've found eggs on the floor of the coop and thought they could be hers. Tonight I found her in a slumped over position looking dead. She moved her head and when I picked her up she started trying to fly away but could only do an odd jump landing on her side. When she lands she doesn't move her one side at all (except the occasional kick of the leg). She is open mouth breathing and looks and acts dead unless you try to pick her up. I am furiously reading all of my chicken disease books but am wondering if anyone knows what this might be and how I can treat her quickly.
Thanks!
Thanks!
