how do you know the difference between moulting and possible other issue like mites? one of my marans is missing feathers on her back by her tail. I do have a rooster, but I thought when a rooster "gets on" his ladies, it's the back of neck missing feathers. could she be getting pecked by the other hens or possibly the duck? it has warmed up in the past few days here, but past two days I have gotten 4 eggs from 4 hens! thanks all!
