I don't have any chickens yet. I am currently planning and gathering information. My setup will be a 10' x 12' coop, and a 17' x 40' run. I have an insulated barn I can use for egg hatching. I want to have a constant supply of eggs and meat for my family of 5. I have a freezer, so I can keep extra birds I cull. What I am wondering is it better to try to keep a rooster and hatch chicks, or just to buy pullets, raise a flock, slaughter them and replace birds as they are culled? I live in an area where there are people selling chicks often. If the answer is to raise my own perpetual flock. Should a make a separate area in the run and coop for newly hatched birds?
