I have 4 hens, 18 months old, all different breeds. At the beginning of summer one went broody and it seemed to kick off some kind of problem and now all 4 are not laying at haven't for at least 4 months. They were previously very good layers. The Americauna hasn't laid at all, the Brahma and the Welsummer lay about once a week, the Cochin who was broody does the best, with about 3/week. I have no idea what's wrong. They eat layer pellets, they get some treats, the coop is nice and clean, they have tons of outdoor space with lots of light, they free range sometimes, there is no trauma or significant fighting (from what i can tell), it's not too cold or too hot, I can't figure it out. The only thing I can think is that they don't all sleep on the roost and the Americauna sleeps in the nest boxes. We love them but I'm sick of buying store eggs and taking care of these free-loaders! Help!!!
