Could the heat do this?

ok so this is the only one that would hold still for the picture and she is also the worst one. She is missing feathers on her neck, belly and by the base of her tail as i hope you can see. They are allowed to free range when I get home but before then they have a very hot coop I would say 100- 110 degrees right now but they also have a 25x30 foot run that is 75 % shade while I am gone. I have checked for mites and found none and I have switched their feed to 20% protein since they like to eat the cat food. but I just started feeding them that today so not sure if it will help. They are one year old now.

Do you have a rooster???

Several of my rooster's "favorite girls" have lost feathers in those areas.

I wonder if they are just molting for the first time. Seems like the timing might be about right.

No Rooster and this has been going on for two months do they mold that long?
