My hens are just coming back into laying after taking a break to molt. So far today I've gotten 7 eggs from thirteen hens and they're not all finished yet. They've always used totally open nestboxes with no problem. Several months back I added an enclosed nestbox on the floor that quite a few of them prefer. Tomorrow I plan to replace all of the remaining open boxes with enclosed ones, the same as the one on the floor. Do you think the change is going to disrupt their laying? Or maybe not since they are already used to the one enclosed box? UPDATE: So I changed the nestboxes out yesterday, leaving only one of the open boxes and the original covered box in place with the new covered boxes. I just checked on things out in the coop. The hens are all squeezed into the old, open box and the original covered box! I shoulda known this was going to happen! If there's any creatures in this world more set in their ways than me, it's my hens. They're just going to have to deal with it. They have three choices - lay in the new boxes, keeping squeezing in to the old ones, or lay on the floor. I so hope they'll pick option one!
