My wife and I would like to get some meat birds. We are living in a small city and the hens would be penned in roughly 65sf. I'd like some advice from how many meat chickens I can fit and how much noose do they make? In a seperate pen I have 3 barred rock and are really quite. I notice the different ways everyone is feeding there animals. Is there a set standards for meat birds? Thanks for all your help.
