Hi everyone! Was wondering if what I was told at the Tractor Supply was true- that this chicken tractor would safely hold 8-10 chickens. My girls are about ready to go out, as they are now about 4 weeks old. So now I'm wondering if the coop is big enough. There are 4 nesting boxes and a long roost plus the floor. I also have a large run that they will be in, so would they necessarily HAVE to all stay in the coop should some of them choose to stay outside in the run? Please help! I want to do right by them, but I'm also kinda stuck with what I have now too! Thanks for all your help and advice!
