We have 14 hens, 4 are EE's. Two of the EE's had fluffy feathers under their chins (so much so that my kids named one of them "Beard-y"). About a month ago, both of them started losing those feathers. And now they both are missing feathers on their back right before the tail. No rooster. All other hens (including other two EE's) are fine. They are free range most days, although in an 18x30 run in the mornings until we let them out. I've watched them and haven't seen any other hens pecking them. I haven't noticed mites or lice, but also didn't fully investigate the coops. I can't imagine it's a protein issue since they get both layer pellets and free range. The EE's are definitely the lowest in rank, but again, in observing them I have not seen any pecking. How should I attack this? Get some Blue kote and put on the two EE's? Add protein to their diet? Treat for mites and lice? Do all three?!? Thanks for any advice!
