My 2 yr old NH Red hen is suddenly droopy. She seems humped up at her saddle area, her comb has bleached out, she's out and about, but not as peppy as usual. I can't check her until later this afternoon, but I will check for mites, fleas, whatever and can dust her down. It has been hot, but I keep them supplied with plenty of water and run a fan for them where they hide under the deck, and give them cool treats in the heat. I've had chickens now for 8 yrs and have rarely had any problems....so I don't know what else to look for ......
