Our coop has been a work in progress since we got our girls (and a few boys that snuck in there somehow). It is coming along nicely and starting to look finished.
They said to have 12" per hen, but these girls shove their butts all on the same roost. The roosts are 24" long and they get 4 on the top and 3 on the next lowest. Since we put this up, they don't want to sleep IN the coop, they want to stay outside and sleep on their new roost!
We even gave the girls a swing.................
Checking out their new digs!
