My after dinner, I found my sisters lab/greyhound mix under the house with my chicken. He was pretty limp and I thought he was dead, but after picking him up, he was in ,more or less, one piece. He was covered in dirt and in a hole she dug, though he has no puncture wounds. He was very still and did not respond to anything. He is droopy, especially his wings, and sneezing a lot. The hen was gone and with him back in the cage, we looked for 45 minutes and then she just appeared. She started to eat and so did he. Right now he is on my desk, on both feet making grinding noises and "zzz" noises and opening and closing his beak and clicking it and sneezing. He still has dirt all over him and is missing feathers along with having a lot of broken ones. He has a few cuts and I am not sure what to do with it, what disinfectant to use. He looks like he is trying to sleep and his wings are droopy. He will close his eyes then open them and stare at me intently. He responds to noises and will look around to see, then go back to trying to sleep.His head seems fine. What should I do? I know I was stupid to leave them unprotected, but I don't want him to have to suffer. I am thinking of re homing them because my sister's dog probably is not going to leave them alone and is ,unfortunately, the best digger and jumper and swimmer and runner I have ever seen. She can get on the roof of our SUV, the counter tops, anything. She swims like a fish, runs like a deer, digs like mole. I think they would be safer with someone else. Not to mention all the raccoons, hawks, stray dogs, coyotes, owls, hawks, opossums and myself. I have never had chickens before and the dog has never seen them, mine has not seen them either, but he does not chase them. He just lays down and watches, even if they are excited, running around, flapping. He just started to try and get his feather back in order and shake a little dirt from them. I don't know if anything is broken or ruptured or anything though, but he did not pull away when he was calm in my hands and I checked him (Is that a bad sign then?). I just don't know, I have enough tears to end the drought and enough anger at the dog and myself to fill an ocean. This is harder than I thought.
