Pale combs, bald butts, ruffled/feather loss

[States family]

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!

I don't think it's mites. If they are the skin would look irritated and red. If she is eating and does not look skinny than you can rule out worms. I think The reason her comb is so pale is probably be from the stress of molting. My rock just finished her molt. If your whole flock Is starting to molt then mix in some extra protein to with their existing feed help them grow out their feathers. Chick start works great. Just keep an eye on her because it could also be just the heat. Hope this helps.

Thanks! I had my husband powder them just in case, cause some of the hens have been refusing to go in the pen at night, we always have to chase them back inside. It was really hot out today though so I'm hoping you are right! I've upped their protein for the past few months, how long does a molt last cause this has been going on for several weeks! I had one hen kinda look funny with her comb turning a white color like speckled but it disappeared after a week or so( the spots not the hen). I'm constantly inspecting them lol! I'm a nerd for healthy chickens hahahahah! So if I see a variance I kinda freak out! There's nobody around my area that vets chickens

Refusal to go in at night is a big mite warning sign to keepers. Other signs are ruffled feathers that might look a little frayed. Tails down and pale combs. Egg laying will decrease.
I would completely clean the coop. Run a white tissue under the very end of the perches, you may or may not see a few spots of red.
Mites are grey but red once they've fed.
Use a good cleaner like poultry shield and jet wash if you can or use a squirty bottle to get into all the nooks.
Use sevin dust or DE on perch ends nesting boxes and dust baths.
Repeat after 5 days to get any eggs that have hatched.

I know your hens are moulting and some signs are similar but the not wanting to go in at night is a big enough reason to suspect mites.
They can become anaemic and if infested will die so it's better to be safe than sorry here I think.

Hope they are ok
