. bare flesh could cause them to start cannibalism which is horrible once they get a taste for chicken meat
It's the tasty blood that causes cannibalism, not the meat.
Separating the chicken can cause MAJOR issues with reintegration.
Finding the cause and treating it is the best course of action.
Lack of protein is NOT the reason for feather picking as many would lead you to believe. Feathers are made of keratin and are only about 2% digestible protein. More often than that is about boredom or behavioral issues.
Molt can happen any time of year, since chickens don't care what all the books say they *should* do... it can be brought on by nutrient deficit, stress, parasites, and many other things... but is most often seen starting around the neck area. True adding extra protein if you feed "layer" does help feathers grow in as feathers are made from 90% protein and its' amino acids. However... that chicken may or may not regrow feathers until true molt. Sometimes pulled feathers will grow back right away but other times if it was broken off they might not come in anytime soon.
One way to tell when you see this kind of feather loss if it is indicative of molt or not... is molting birds will have pin feathers coming in to replace the lost ones. Molting birds will also most often NOT be laying as their body must use that energy to grow feathers instead of eggs. Also molting skin looks fairly normal and light pink... not red with scabs or angry.
