So my chickens were in a PVC coop, covered with a tarp, and had a nesting box that was a tote with a lid. They were there for a year and I felt they needed a new place so I moved them to an very large A-Frame coop. They have enough place to be in the run and I have a platform for them to nest on that is separate from where they roost. I know the coop portion is small but they don't have any problem fitting all 4 in there at night. So the first week I put their old nesting box in the run portion and they laid eggs every day in it. Then I took it out and no eggs. I was lucky to get 1 a day. So I figured my nesting boxes weren't up to their standards. I covered the clear roofing panel with a tarp to make it dark. I cut down some old totes that were similar to their old ones and put them there. But still they won't nest in them. I'm just out of ideas on what to do. They will get in and move all the shavings out but no eggs. And I know my girls, they can hold it until it drops out somewhere.
