Are they slow to learn or do they need somekind of special nest? 3 of the 4 just started to lay, the other one started last fall. The one that was laying, does it in one of the lower nests. The 3 new ones lay on the floor of the coop, and I just found one outside on the ice!! I have put them in the nest so they can see it and they won't lay there....what do I do??? any helpful advice woud be appreciated
