The last few hatches I've gotten a couple eggs that did not hatch out, but that had live chicks in them. On opening them after the due date I found that the chick was essentially alive, but looked like it was too large for the egg and was cramped and twisted around on itself. I felt bad throwing it to the hogs, but it was obviously not going to survive. Is this natures way of trying to grow a larger chicken? Granted hybrid vigor is a factor, I'm using a Sussex rooster and red sex link hens, and one very dominant barred rock 'Momma Hen'. I think they are from the RSL's as none of them have been black so far.
