So.... health problems after 8 weeks, no not all the time but very often. What are these hatcheries doing to get fertile eggs to sell chicks? Are they all lab grown or something?
I've heard they have a huge problem breeding because of the large breast and weak joints.Aren’t they made by breeding Cornish and Plymouth Rocks? I thought they’re hybrids, like red sex links, so they wouldn’t breed true.
This or something similar is how it is done.The Cornish Cross is made from 4 different lines. Grandparents produce the parent lines which are bred to produce what is called a "terminal" cross. It will never reproduce the way its parents or grandparents did. You can get them to breed with much care, but the breeders do a lot better a lot easier. Not easy, but easier.
