only contemplated, after BDutch wrote about hens co-brooding. The pin through the tenon under the base of the divider supports the nest box base, and it might sag if the divider is removed. That would not be a structural failure, but might resemble an old and worn out double bed mattress that tips both occupants towards the middle methinx.have you ever experimented with removing the divide between boxes? Even just for regular laying and not for brooding.
