My chickens have prob about the same amount of space as yours will have, however I am going to rearrange the whole setup because right now part of it is covered and part is not, I had it all netted and with the heavy snow we had most of the netting came down. I worry All the time about them out...
It's a matter of large area with no cover and take a chance with hawks, owls etc OR a smaller area fully covered and safer chickens and that's not even a Sure thing, I lost 5 last spring to a small hawk that got in despite the netting .......having chickens brings heartache sometimes, they are...
