I am fairly new to raising hens. I have 3 girls who are free range, they are going to be 2 years old this spring. They are fed layer ration with oyster shell mixed in, their favorite treat is shredded cheese, and I've recently added a protein and vitamin supplement pellet which was supposed to be mixed into their feed, however they do not seem to want to eat it. About 2 1/2 months ago we built them a larger coop that would accommodate a few more hens this coming spring and provide better shelter through the winter. The girls definately got stressed out by this and I can only assume that the stress may have triggered the molt. All 3 began to lose feathers and stopped laying. This was in early October. None have layed anything since. Two of my girls have all their beautiful feathers back but one is still looking very raggedy. Most of her breast feathers are gone, some on her neck and her sickle feathers haven't returned. I've checked for mites and see no signs, she is in the middle of the pecking order so not the one who gets picked on, which is rare for my girls anyway. Any ideas on what I should do?
