We used to raise caged chickens, so we just converted the cages into nestboxes by removing the door and adding some straw:
I also built three wooden nestboxes and sometimes they lay eggs in there, but they mostly lay eggs in the cages that were converted into nestboxes:
Although 90% of the time they lay eggs in the nestboxes, there's still that 10% where they lay eggs anywhere. So that's one of the challenges right now. We have been averaging about 25-30 eggs per day out of 55 hens, so I think that means the hens are doing well.
