I built this 4 x 6 coop last year for my 6 chicks. I'd like to get 3 more chicks in the Spring (but no more, per the city), but i feel their coop will be too crowded. I was thinking, one solution would be to build a smaller, raised coop next to this one for nesting boxes and feed, and turning this current one into, just roosts. Does anyome have experience with a design like this? Do you think it would work for the hens? I cant really think of a way to expand the current one, enough, and still be able to clean it easily since it is not a walk in. Attached is a picture.
