What is the problem with breeding Cornish Rocks or Jumbo X Cornishes? Is it the huge size of the chickens and subsequent fatigue and clumsiness or is it a sterility problem? Possibly a problem relating to positioning or mounting......therefore fertility being achieved better by artificial means??? Is the problem mainly isolated with the cockerals? If so I can use from another big breed. I am wondering because my husband wants a few, but mainly for the huge eggs. I, on the other hand, am content with my RIR eggs and would want the breed for meat. But I don't want the hatcheries to do all my incubating for me when I can do it myself and save money. Certainly there is a way to have fertile eggs with the Cornishes, otherwise how did the hatcheries get the chicks? Its just that if I can fill up an incubator with enough eggs to get about 50 chicks, the price I would have paid for that amount of chicks by mail order, could have cancelled out at least 4 sacks of starter grower. The chicks could each weigh 1 or 2 Lbs.
