I have 5 Black Sex Links about 5 months old and have been in their new coop about week. Before that they were in a pretty small (2x4) area. The coop is 4x4 with an additional 3x1 nesting area (3 independant 1x1 boxes) and nice size run. But each night when they go in the coop, they all 5 squeeze into 1 nesting box. What the...? I have roosting bars, nice big area for the 5, why would they do this? That's like buying your kids each a new bed just to wake up the next morning and they are all in the same bed.
