I believe a few of our hens are molting. At least that's what it looks like to me. I see no lice or mites, and i don't see any pecking spots where someone is pecking at them. The black Austrolorp has been going through this since late fall. The Buff Orpington started late in November in a few areas. I had made some little aprons for them and put them on all the chickens. I was only going to keep them on for a few weeks but these two never did seem to get new feathers in, then it started getting cold so I just kept them on until just a couple weeks ago. They are eating fine, they get crumbles feed at 16% and layer feed mixed together, plus grit and oyster shells offered in their own feeders. I also give them meal worms occasionally along with some scraps.
I have been doing artificial lighting, so they have about 13 hours of light. Does the artificial lighting stall their molting process? They are making me doubt myself on what I'm doing, what should I be doing, etc.
