I have a beautiful and docile Americana that was broody for a week and a half and I had to fly to Florida( Wednesday) for a family/health emergency. Returning home last night, my husband informs me that one of my hens was attacked , but he had no idea how/why/or when. I went to the chicken coop and there she was on her eggs. I hardly recognized her. She has no feathers on her back, her neck or her wings. The skin has already started scabbing over. My husband, not knowing my chickens and not wanting to upset me, when he found her Friday night, locked her in a separate section in the coop to keep her away from the flock, which he didn't know , but kept her from her eggs as well and she escaped when he opened her section to check on her on Saturday morning( she went to her eggs) He said he didn't want to upset me by telling me about her while I was dealing with my family. I know that her eggs, which all five were developing when I left, have to be disposed since she was off of them for more then 12 hours. I immediately put her and her eggs in a area away from all the other hens, but she wont lay on them and wants out of confinement. With the fact this mauling was done on Friday at sometime , what can I do, if anything to clean her injuries? She has a nasty one on the back of her head and on her side. I truly believe it was my daughters new puppy because Saturday my youngest sent a pic of the puppies cheek where it had a stab wound in it, I'm pretty sure my rooster went in the hen house and saved her or the puppy wouldn't have stopped. Yes, the puppy went through the chicken door and got this poor hen as she sat on her eggs. Our daily temps right now are 30's at night and 60's during the day, but should I still be worried about flies? She is eating 'cause I took her some protein to help with her feathers when I got home and tried to make her comfortable. I don't want her to suffer if anyone with experience thinks she's too far gone. But, she is clucking and eating as we speak. My best friend is a Vet and is going to give her a shot today of antibiotics.
