So currently we have some big babies in the brooder that are ready to go outside. They are flying!! Anyhow, we are building a grow out pen that ww hope to use as a tractor too. Right now we have 5 leghorns, 3 chocolate orpingtons (LG bantams) 1 barred rock and 1 buff orpington. The run is 8x4 and the coop is 2x4. It'll have 2 roosts both 2 ft long and plenty of headspace (3ft high) to add more roosts if needed. I know the idea is 4sqft in coop and 10sqft in run but with a tractor clearly we cant make it much bigger than what we have. My question is, at the point we have to take some babies out, how many should I feel comfortable leaving in? I'm thinking all my leghorns and my barred rock. So 6 total.
