ISOA for Bald underbelly on 2 YO hen, soft eggs, now seems lethargic

[V4tea]

I have a copper Maran hen that has had a bald underbelly since April. I have checked for mites. Up til today she was eating and drinking fine. She has continued to lay, but her eggs are getting soft. About 3 weeks ago I soaked her in epsom salts as her exposed skin is red. I soaked her again today and will check for mites again. There are 2 other hens with her and they have been fine. I feed them 20% feed, scratch, meal worms and occasionally sunflower seeds. Any ideas of what we could be dealing with. I am new to chickens.

Is she molting ir going broody? Is it where the roost rubs?
Do you provide calcium supplements?

Would she be molting in Maine, from April to now? We didn’t think so but I am new chickens. She was in the coop a while today and is very stand off-ish, I am giving them Poultry Cell supplement brand.

Also we do not have a rooster. Would she be allergic to anything that makes her skin red?

This is the hen.
