I have 3 chickens just over 3 months old and we build what we thought was a perfect little coop for them modeled off many of the coops on here. So all three of the chickens sleep and mess in their nest box at night instead of using their 3 roosting poles at various heights. They are not laying obviously yet....once they start laying will they stop sleeping in there? The roosting poles are made out of like rounded off 2x2s ballaster (sp) type poles. The nest box is opposite of the roosting poles, and the food and water are on a different wall as well, so everything has it's own area. Any help would be appreciated!!!
