I lost 2 chickens in the last 2 days due to unknown predator. We thought hawk, now thinking a mink or weasel. This one (Penelope) was attacked while I was eating lunch. We did not hear a sound and she was attacked less than 10 feet away. I came outside to her laying down and bleeding. A few minutes later she was back standing upright and screaming. I brought her inside and isolated her. I cleaned her wounds with water and I believe the bleeding has stopped or slowed significantly. How can I help her more? Stitches for a wound this big? Her neck is basically exposed. I read to get the medicine for infections but I will just use neosporin now since I cant leave the house right now. Any help is greatly appreciated. I really want her to make it. She is my favorite hen and only 18 weeks old.
