Um, I have one Al, the NON predator safe one. I set it up for integrating 4 white Chantecler pullets I never got. I left the door open because "why not" and some of the girls WERE roosting in there at night by choice. The coon didn't show up until recently (possibly 'rehomed' by some A-H??) and as it happened on the night we found the hen, all the girls were in the safe coop. I would have put the found hen in there but she needed to cool off and get un-broody so I closed her in the other one as it has no nest boxes. I would have put her in the buster but Echo was using it.
I can add a lot of hardware cloth to that second coop so it is more safe, not sure how I explain to the hens "mean girls go in this coop, those getting pecked go in that one". There is ~ 8.5 sq ft of floor space/bird in the safe coop, 24' of roosts at 4' and an 8' one at 2'. These hens are going out of their way to peck the lower ranked girls. Just POed that they are in jail I guess. The lower girls were already showing signs of abuse but it has gotten much worse since I started shutting them in.
