Kinda small.so 7 are roosting together at night. The coop is 5' X 6'.
Need 12" of roost length for each bird.....looks like roost is only 5-6' long, which might be OK since it's low(they don't need to fly up). But roosts should also be higher than nests(to avoid nest sleeping and the resultant poopy nests), and if the run roost is higher that's one reason they are choosing it.
Where are you going to fit the 8th bird and her offspring?
Is it also weather(rain, wind, snow) proof?"Outside" for me is in the hopefully predator proof
