So, last night as the chickens are settling in to the coop for the night, I notice my bantam OEGB cockeral making a little "nest" in one of the egg boxes. He circled and circled, then settled down, using his beak to fluff up the pine shavings. He sat there for a quite a while and while he was in one box, another OEGB pullet started doing the same thing in another box. These are my babies and are about 12 weeks old. At one point, another OEGB pullet joined the cockeral in the nest box and the two of them sat there together. When I checked on them about an hour later, all 3 were on the roosts. Are they getting ready to lay eggs already? What's the cockeral doing in the nest box?
