Ok so we have 8 laying hens (no roos) for food eggs in our current pen and coop. It's pretty big for just 8 hens. We also have another "shed" that runs along one side of the pen and we are considering converting that into another coop, running another piece of fence through the pen to separate them and getting a Roo with a new flock for fertilizing eggs to raise meat birds and also possibly to sell the laying hens at a local sale barn. Does that make sense? So my questions are: 1) is splitting the pen into two sections and keep them separated necessary? Otherwise how do you know which are fertilized? 2) how many hens and Roos should I get? 3) should I let them sit on the eggs themselves or pull the eggs and incubating them ourselves? 4) what do I need that's different from my other flock for raising and hatching chicks? 5) anything else I should know?
