I have 4 chicks coming on the 12th and I have 9 bantam eggs in the incubator. The coop is almost done we built an 8 x 8 x 6 coop, lots of ventilation and 4 shed windows with hardware wire on them. I have a metal fence that is 7 x 8 x 5 and since I am home all the time I intend to free range I have the run more for days I have errands and cannot be here to let the free. Is it large enough for the time they will be in there or should I add more space?
