My 6 young Buff Orpington hens are laying (a lot), and I had a 4-slot wood nesting box from a kit that is 11" x 11" x 12" inside the boxes. The hens barely fit, look really crammed in there and they can't stand up. I watched one lay an egg and it seemed like some repositioning and fidgeting around accompanied getting an egg out, so I built them 3 bigger boxes that are 18" x 18" x 12" inside. Put them in and the hens don't seem to like it. Do they just hate any change by default, or do they prefer to be in the nesting box super tight? I was surprised I couldn't find extra large wood nesting boxes so I had to build them. Now I'm wondering if that's because no one wants that.
