My chickens are currently in a large barn using an old wooden work bench as just one big communal nesting box. My current Orpington also uses the wood bench with the others so I don’t know how she would fit in a standard size nesting box. I am also switching over to pretty much all English Orpingtons. I am moving the chickens here in the next month to a converted 16’x60’ lean-to so I can have actual large pens for brooding, egg laying chickens, cockerel pen etc. . Overall it will be much easier to manage, clean and separate. I am at the point where I’m looking to either build or buy nesting boxes. Everything pre-made the nesting box interiors are the standard 12x12”. Now it would be easier just to spend the extra money to have pre-made nesting boxes for each pen. I’m wondering though if 12x12” is going to be too small for my Orpingtons and if I should just build custom nesting boxes instead. If I did make them I was thinking of making the interiors of each box 14” deep by 16” wide. So my questions is to those with Orpingtons what size nesting boxes do your girls use?
