I'm very new to all this, but I came home today to find one of my newer chickens acting different. She was huddled in one spot looking a little droopy. Her comb is droopier and a little more pale than usual, her tail is definitely drooping, and she just seems slow and lethargic. I've separated her from the others and gave her some water, which she seemed very eager to have. It's in the 90s here today so I'm not sure if maybe she's just dehydrated? Or could it be something else? I checked her over and everything else looks normal (But again, I am new to this so I may have missed something). Any suggestions for what to do next or remedies to try would be so appreciated. Thank you!
