Hii, So after doing all my research and months of building our dream coop we started having a problem others on BYC were experiencing. Girls wanting to roost on the edge of nest boxes and subsequent pooping in the nest box bedding material. We would go out every night and physically put them on one of the many roosts we gave them......still a handful would end up on the edge of boxes. I thought of a variety of things I could do to prevent it and finally decided to use the idea of a fellow poster here whom had made nest boxes from plastic buckets with a thin piece of plywood cut in a Vee on the front to keep in bedding. i had considered a thin wire across fron, thin piece of metal, etc...Anything that they would not be comfortable roosting on. Had plenty of 1/4 " luan in work shop so just cut a few pieces the width of my two boxes, cut a vee large enough for our biggest , fat assed bird to still be able to enter and attached them with screws. The steep angle and thin material is not condusive to being comfortable for roosting. So, I think (knock on wood) the problem is solved. Here are two photos of before the upgrade and after. Been 4 days and no one roosing on boxes and more importantly, no poop in boxes. Thanks for checking this out and hope it helps someone else who has had same problem. Erik Before photo. Might add this is an older pic and have since added second roost and poop trays. After photo. Can see another set of roost and poop trays now in place. total of 24' of roost space. Here is a shot of overall picture of some of the girls coming in for the night using roosts and ladder/ ramps.
