Hey guys, I've got close to 60 hens. Some are were born March 3 and are laying. Some were born 3/31 some of those are lying. And some were born 5/6 and not laying. My problem is that some are pooping n the nest boxes. What could I do to help with this problem? It seem like more of an issue on the top row of boxes. My lowest roost is about the same height as the lowest roost. But there is 72 foot of roost that is higher than the nest box. Please help!
