Something is indeed wrong with your flock, but you haven't given us enough information to work with.
Depressed
behaving chickens may be sick or suffering from stress from a predator attack or there may be parasites at work, both internal ones and external ones.
Has anything occurred that would put significant stress on them?
no... I do feel like the pecking order has changed and they picked on two hens for about two months
What exactly is their behavior beyond just wanting to hang out in the coop? Are they vocal? Are they active? Or are they immobile and standing around all fluffed up with shoulders hunched? Photos? Not vocal unless the Queen bee gets onto one of them
one of them is fluffed up and hunched
What does their poop look like? Photos?
What do you feed? Protein content in the feed? What ratio of treats to commercial feed? Let me check brand and info. I tried to change it to see if that would help. I only put out scratch three times a week
Have you checked them individually for lice and mites? Have you checked the coop at night for mites on the perches and on the legs of the flock?
I will tonight
Are there any symptoms of illness? Sneezing? Bubbly eyes? Swollen faces?
The one that is hunched up is the only thing that I see is that her comb looks a little darker on the ends
And where do you live? Country? Climate? Season? Granger Texas it is 50-60 degrees
