I built an 8x8 coop and had plans of getting different breeds of hens and 1 rooster...I bought 2 cochin pairs and now want to just have pairs...My 8x8 coop is now going to be 3 4x5 coops with 11x5 runs on each....and will have to build more for upcoming chicks that are now 3 weeks old....Moral of story is if I would have thought about it first I wouldn't have wasted time building a big coop and then tore it down to build smaller ones....
