I'm telling you if you do this go with day old chics not eggs. Incubating and hatching eggs is a very tricky business. Or if you don't want to do either just buy some breeding stock and go from there. Beware Cornish sires can be VERY spendy. We are talking about some of the most advanced, selective breeding in any of the animal kingdoms. Also I know a lot of the breeding that's done with the breeding stock anymore isn't really breeding- it's AI (artificial insemination) and that's hand work which is part of why good breeding stock is so expensive.
