No tails and some bald backs and other spots.

They're just entertaining , nothing needed for them. :]

Ok my parents kept telling me that they were probably just bored cause it’s just dirt and there’s not much for them to do so we were trying to do stuff to keep them more entertained

You could add some roost bars from old wood, rake some leaves or hay in there for them to scratch through, they'll love it.

Ok thank you!

I'm thinking your parents are probably right and the boredom is resulting in feather picking. Have you considered expanding their run, perhaps with portable poultry netting? Do they have a dust bathing area?

 

[Hannah J]

Their whole run is dirt that they dust bathe in everyday. I’ve tried giving them a fist bathing spot but they choose random spots around the coop anyway. We also have lots of predators so I’m too scared to just use netting

Hey, I’ve had something similar happen with a few of my hens. If they’ve been missing tail feathers for that long, and now some have bald spots on their necks too, it could be a few things.
You already ruled out mites and haven’t seen any pecking—so that’s good. But sometimes feather picking happens at night on the roost, and it’s easy to miss, even with a camera.
Molting could also be the cause, especially if they’re close to two years old. Some hens just don’t grow feathers back quickly, especially if they’re stressed or if it’s been really hot lately (which you mentioned).
You might want to check their feed—low protein can slow down feather regrowth. I’ve had better results when I give mine a little boost during molt, like scrambled eggs or a higher-protein ration.
Getting four eggs today is a good sign, though. If they’re eating, acting normal, and still laying, it’s probably not something major. But I’d keep an eye on those bald spots and see if they’re getting worse.

Just an idea: I have one that pecks her own feather off and she looks like yours (no tail feather and a little bit off of her back and chest, places where she can reach). She came to me 3 months old and already like that (the other two that came with her do not have the problem). I think it could be because the environment was stressful (maybe too many birds) and she got used to doing that… I’ve been meaning to put a vest on her but it’s too hot to do that now… so I’ll probably wait until November or so.

Looks like depluming mites have attacked them. We use Elector PSP which works wonders and requires no egg withdrawal period. It also works on other wee beasties that attack our girls periodically. Lastly, it also kills the flys that may be in and or around your coop and is harmless to cats and dogs. Very expensive but you only use a small amount in a bunch of water. We don't buy in the small amounts that are often offered to small chicken owners. Very often it is cut with water to enhance their profit. The real stuff is about $150 but it lasts forever and you know exactly what you bought. We treat the flock 2X in 2 weeks as well as treating the coop and any nesting boxes to make sure they don't come back. I'm not an expert on this, but we have a contracted Vet who comes and visits our flock and makes sure they are healthy. These are her recommendations and I am happy to share her advice with you

OK. Pause. Take a deep breath, then another. You are doing fine!

I also have a naked butt hen--her name is Tush. As she preens, she plucks out the feathers at the base of her tail for a reverse mohawk. She also plucks the feathers under her wings and is bald there, too.

I treat her for mites. Mites are microscopic individually and are usually only "seen" in massive infestations, usually because of fecal matter left in their wake. I scrub their night perches with bleach whenever I treat them. They free-range and are never in the hutch except to sleep, so your results may vary.

Personally, I wouldn't worry too much about the feed, etc. right now, in the middle of summer. My chix always stop laying in the summer; it's just too hot. Your birds look alert and healthy. Treat for mites, and revisit the rest when it cools down.

Ba-gawk!
