I have an 18 wk welsummer. She's usually very friendly and curious. A little skittish, but will eat out of my hand, doesn't mind being petted but doesnt really like to be picked up. Today is Saturday Wednesday she was fine, she was out side with the other 4 hens, all the same age, been together since 3 weeks. Thursday, my husband noticed she wasn't really socializing with the others. He said one wing was drooping, but it isn't any more. She slept in the nesting box. I thought maybe she was getting ready to lay an egg. We have golf balls in there right now. Friday night I came home from work, he said she still seemed sad. Was kind of laying in the window of the coop, in the sun. Still not socializing. He said she was walking funny and wanted to curl her feet. We brought her in the garage last night and kept her in a pet carrier with a light bulb for heat. She was eating layer feed. Not really drinking too much. Occasionally opening her mouth. Saturday she was standing, her feet looked normal. I put her in with the other birds. It's very cold out. They all went outside, including her. She was kind of hanging out by herself. She came back and walked about half way up the ramp to the coop and half stumbled, and sat and rested for a couple minutes. She came back into the coup and went right into the nesting box. She is very quiet still. I brought her back into the kennel in the garage. Made her a scrambled egg with 1/2 bananna and she ate most of it. Not really drinking much. Some normal poop and some diareah in kennel. I cleaned the poop out of the kennel and brought the kennel in the house. She has been standing closing her eyes. She has been lying down. I mixed up some amprolium into the water, just in case it is cocci. She won't really touch the water. I put some in with her food and now she won't eat her food. She picked at it and made some clicking noises. She opens her beak some times when she breathes--not a lot. Doesnt really want water even from an eye dropper. I didn't put a light in with her now that she's in the house because I don't want her to get too warm. What else should I do? The rest of the chickens are acting normally so far.
