So my orpington chicks are growing rapidly and the construction has begun on the new coop. The design I have made is a 4 x 5 (including nesting boxes) coop and an attached 4 x 8 run (or 4 x 12 including under the raised coop). We are hoping to end up with 4 to 6 hens once ours are old enough to properly sex. Just wondering if this will be big enough for them. They will get some free range time outside of their run as well. Any info/advice is greatly appreciated.
