I just spent the last seven weekends building a coop and run for our 7-week old chicks. We have 4 chicks total. I am just now getting nervous that our coop is too small!!! Our coop is 3' x 3' x almost 3' high, with an external egg box. Our run is covered and there is shelter beneath the coop as well. We live in fairly temperate Pacific Northwest, so we plan to let them in their run everyday. The run is 8' x 9' x 6' high, and covered, as I mentioned. Will my four hens be overcrowded?
This photo does not show the run's roof (corrugated roofing panels at a mild pitch) but gives a good idea as to what I'm talking about. The chicks are set to go out next week. Should I rethink my plan?
