So being our 2 girls are going to be introduced to our chicks in a month we have got a new coop. It should arrive in 2 weeks! Depending on the gender of the chicks we will have anywhere from 6 to 2 (no cockerals allowed here) if that's the case we'll get some pol girls and having 2 coops will make the quarantine easier. It says up to 12 but my calculations that 9 would be a maximum for the right amount of space. They free range when we're home so it'll be only be when I'm at work. I wanted to build one but hubby took the easier option and picked this one. We have a similar make for our 2 which says 4 chickens but I wouldn't put more than 2 in there. It's weird that they seem to think more chickens can fit.
