Today I candled my eggs 5 days in that I got shipped from a BYCer. The eggs were packed well and looked really good. The seller was obviously very conscientious. That being said, I noted that one egg was developing and the rest were doubtful. Now, many of them were dark marans eggs, but of the three EE eggs, one was definitely not fertile or too damaged from shipping, one was debatable, and one was definitely developing. I thought I might have seen veins and an embryo in a Marans egg, but beyond that who knows? I threw out the one I was sure wasn't developing and kept the others. After having several successful hatches of eggs from my own chickens in a 7 egg incubator (7/6/6), I can pretty much say I have a good record, so it isn't anything I'm doing. I think that hatching eggs from the mail is risky and not worth the money. There are too many factors going on that don't come together with shipped eggs. That being said, please note that I am NOT blaming the seller. I think that shipping is just too hard on the eggs and it's unlikely that I will get the breeds I want unless I buy chicks. I'll let you know what the hatch rate was, but I feel I'll be really lucky to get 2 birds. Sigh.
