With two people putting this coop together it takes about 2 hours without any distractions. This coop is okay for small breeds of chickens like silkies maybe 1-4 birds. However if you are putting larger birds they will need more room inside the coop and out. The height in the outside run is large enough to add a branch or two for them to swing or perch on. It would be perfect for rabbits or maybe 1-2 chickens. I will be adding on to this coop and extending the run.
