I was out doing my daily routine feeding and water my hens. We have roughly 18 mature hens,1 rooster and about 7, 5 month old chickens. While doing my routine I noticed the one hen, a road island red, her comb was very pale. She wasn't lethargic and she was eating. I caught her to feel her crop, and it was slightly balloon-ish but had food in it (not tightly though kinda felt funny to me like maybe she drank a lot of water cause it was really hot today.) most of my hens stopped laying, I thought it was from molting and now I'm not so sure. Looking up photos online I thought it might be the work of red mites? Their feathers are ruffled mostly, they're having some baldness on their butts, and about 2 have balding heads. I'm not seeing scabs or any feet problems. Could this be a lice and mite issue? I bathed them all about a week or two ago just to get them cleaned up a little bit before fall, and do a little check over on all of their health. The one hen, the only, had what looked like bunches of gray material around the base of her feathers near her bum. I tried to get it all out but it was so stuck that I just scrubbed them really well, it just wouldn't come off. Are those mite and lice eggs? If so how the heck do I get rid of them!? Best treatment advice please!
