I am just learning. I really need more info. Are these all pullets? If they are birds for showing this year there is the concern of feather condition. And I'm sure it depends on breed. Show birds are frequently kept penned without the 10 sq ft of space that many of us have come to accept as normal. That would be a huge freestanding cage. But in smaller quarters, its harder to keep their feathers in top condition with crowding. If they are featherleg it is more difficult. Many times they are kept in trios or quads for breeding, unless you're pen breeding, but all info I've seen on that has had them on the ground. And I'm sure for 4h birds the expectations are not the same as for profrssional show birds. Somebody with some experience in this should chime in.
