I've done a search on this, but I'm still unsure. Can you seasoned chicken owners help me? We live in a really urban area, but are thinking about trying to raise meat birds. Would it work to order 25 Cornish X, raise some to game hen size and slaughter at 3-4 weeks, then let the rest grow out and slaughter at 8-10? They'd be in a tractor, but wouldn't get a ton of "pasture", since we don't live on a lot of land. How much feed might I go through for this kind of setup? How much space would you give them? Want to raise our own meat birds, and we were thinking that this way would help us cut down the intensity of the poop mess I keep reading about as they get bigger. Thoughts?
