So we don't hijack the previous thread here's what I said: Right now I have a problem with my MW hens not finishing their sets. They smash the eggs while they are hatching. This is a trait I want to cull out and I may have to bring in outside hens to accomplish it. Once I accomplish that goal, I will probably line-breed my flock. When you think about it, how much genetic diversity can there be in MW's? They all originated from 6 birds. Anyone who breeds MW's is line-breeding or am I missing something here?
