I have 6 hens that just turned 3mos old. They started laying a week ago, and I hadn't built my nest boxes yet. I built them the day after I found the first egg. My coop / nest box is modeled after a design I found here ( https://www.backyardchickens.com/web/viewblog.php?id=30865-coop ) The problem I'm having is that the hens keep pulling all nesting material out of the boxes, then poop in them. I've put golf balls in as I saw that in a post, but they keep pulling everything out into the main coop area. It's been nearly a week and I'm worried that the problem might be that I hadn't built the boxes in time. (I honestly did not expect them to lay at 3mos old) Any recommendations? Thanks for your help!!!
