They get along pretty good. I think a few feather have been pulled on a couple of the girls as loss was on their head or neck. I have plenty of space for them in the run and coop. Diet - layer feed and treats. The like all the dandelion leaves and flowers that I pull. Never saw a bunch of feathers that would have made me go - hmmmm, what's up.Feather loss when they are not broody, may be from feather picking. That can happen due to overcrowding, boredom if not getting outside, too much light inside the coop, and not enough protein in the diet. Some peck each other on the roost in the evening.
