Just finished putting together my nest box (aside from some roofing and a lock) and was weighing my options. Partitions to make three 12" x 12" boxes or just leave the three entrances to one big 12" x 36" communal box? What say you, BYC? Pros and cons for each option? My flock is half second-year hens and half first-year pullets just reaching point of lay. They are starting to mix better but the groups still like to generally segregate.
