Trying again is the only answer. i have some veining in eggs that still have roaming air cells from the postal gorillas. So it can work. Heck I have one egg from the busted hatch that went to 113 that is still going. I don't usually give up until a fat lady sings well. Im fat and I sing poorly, I'll know the difference. chuckle. My Mad Hatchers Batch is rolling right along, old eggs, refrigerated eggs, dirty eggs, misshapen eggs, over heated eggs, and there is detectable veining in a lot of them. I won't toss until at least day 14, some embryos are just too hard to see. I'll candle again in a few days, just because it makes me happy. Don't know if that last chick from the busted hatch is going to hatch properly but I will give him a chance. You can do it, it takes luck and practice. its worth it in the end. Best of luck next time!
