I have a Rhode Island Red that is over one and a half years old. When I went outside this morning I noticed that she looked a bit off. I didn't think much of it but when I went out this afternoon she is looking really bad. She is hunched over and doesn't come when I call her (she is always the first one to come when I call). Also, she pooped and her poop, which is green, is bathed in a puddle of clear mucus. I looked up at the poop board and noticed to very sloppy poops up there as well. She is currently in the garage in a box with wood shavings, water, feed and plain yogurt. Does anyone know what could be wrong with her and if she will live or die??? I just realized that two nights ago would be christmas day. On christmas day I gave my chickens, plain yogurt, banana, sunflower seeds and oatmeal all mixed together. Do you think that she might have ate so much that she is now sick?
