I have a few questions... I have 4 hens and roo that are 16-17 months old. The hens have been laying since last August. I got eggs all winter, but this summer I get about 2 a day. One hen lays pretty consistently, 2 alternate, and 1 doesn't lay at all. How do I know if they're molting? Yes there are feathers in the coop, but I also have pullets that are around 5 months old, so everyone seems to be contributing feathers. How long should the hens not lay? They free range, and I am sure that they aren't laying else where. The rooster is pretty aggressive with his mating. One hen seems to have scratches/bald spots on her back. Another hen has some of her wing feathers destroyed. (near the top, close to where they touch her back.) However, he is a good protector, so I do not want to get rid of him. I've read that some people separate the rooster for a while... If I did this, how should I? How long? I also want to be sure that the chickens are able to protect themselves from mites. Again, they free range, and they have their favorite dust bathing spots, but is that enough?
