Hi, Our four girls are now 19 weeks old, getting red in the face and I think might be getting ready to start laying YEA!! So my questions are: 1. They were all sleeping on their roost, but now they are all sleeping in the nesting boxes (three boxes). Should I block the boxes for a while, or will they figure it out on their own? 2. They free range in the yard most all day (with access to their coop). Should I keep them in their pen for a while to train them to lay their eggs in the boxes or will they figure that out as well? Thanks so much. Don't know what I would do with out Backyard Chickens People!!
