Geez, the deformities sounds awful! I’m really surprised that our fertility has been so good! Larry, our 2 yr old BCM roo, was only recently added to the hens, and he looks like a ridiculously incompetent roo at mating, but all of the eggs were fertile! Someone said that the bloom of BCM interferes with water loss from the egg, so I expected I might have a small air cell/wet chick in our eggtopsy, but that wasn’t the case. Do you see them pip through a blood vessel at the air cell membrane and bleed out very often? I’m wondering if I can tell whether my vaccination technique killed that chick or if it pipped through the vessel...
No, I've never actually lost one to pipping through a blood vessel. I did have a really bad one like you're describing where the entire top of the shell had dried blood but it was a blue egg and it hatched like nothing happened. I was surprised to see it as I was cleaning out the incubator, lol. Since it was only one of your chicks it's possible it was just a fluke!
