Some roll to the front. Some roll to the back. So, which way is most convenient?
We tried one design posted on here, but we had a few issues.
first, any bedding gets in the way of the eggs rolling into the reserve areas.
any trim or petite pullets/hens? Then you’ll likely find one or two that like the confined space of the egg area. Yes, we often had to remove a particular hen from the egg area.
so, considering previous point, make the access opening narrower.... then some eggs won’t go in. A determined (or scared or bullied) pullet/hen figures out a way to get in.
Somehow some water intruded and buckled the angled floor. It was still useable, but by then, the design had outlived its usefulness and we replaced the nest boxes with another design.
maybe when we can travel more once all kids leave home, we will revisit rollout nest boxes, but for now we went back to a more basic nest boxes.
