So I keep seeing s omany postings about hatching eggs, and adding to flock and I have several questions: -I am starting out with a dozen (plenty of room for more) -How many do you currently have? -How many do you add each year? -When people talk about hatching out chicks-are you then turning around and selling them? -When they are your "babies" are you still getting rid of them after 2 yrs? I want to buy an incubator and hatch out some babies, and add a couple hens here and there as I find a new breed I like but: -How do you introduce new chickens to your flock? -What do you do with all the roosters? -are you risking disease with your established flock if adding new chickens? How do you manage this? -Is there problems with mixing any particular breeds?
