I need help. I have a Delaware hen that is about a year old. She isn't feeling well, I've never dealt with a sick Chicken so I have no idea what to look for so I guess I need some ideas. Her comb is pale and flopped over, she is weak, and just looks so miserable. I knew as soon as I went out that something was wrong because out of all the chickens her and her "sister" always greet you and she didn't. She was just standing in one spot and slowly made her way over. They were all wormed about a month ago and we noticed mites on 2 of the chickens about 3 weeks ago so we treated all of the chickens, house, run, etc. I checked her over really good, just in case, and saw no mites or mite eggs. I put her in a dog crate without a bottom in a breezy and shady spot with water right there next to her. She drank and pecked around in the grass. She even stuck a foot in the water. I was hoping maybe she had just gotten too hot because it's been extremely hot but she wasn't acting any better when I put her up for the night. Could it still maybe just be heat exhaustion? All of the other chickens have been hot and panting but there combs are still red like they should be. Please any ideas would be greatly appreciated.
