Is it necessay to keep the nesting boxes off limits to the girls while they are still eight to ten weeks from egg laying? When I built my coop I built it with access to the nesting boxes so that it would give the hens alittle more room. When they go in for the night they all take there place on the roost and I only find them in the boxes on rainy days when theyare in the coop to get out of the rain, other wise they are in the run. I have read in several post about people blocking off the boxes, is this because when they begin to lay they won't use them? any thoughts?
