Hello! I'm a new chicken mama. I've recently started selling hatching eggs and had someone write to me and tell me that none of my eggs took. He purchased the eggs from me on Sunday when none of them were more than 3 days old. Some of the eggs had been hatched hours before being sold. The eggs were unwashed but clean. They were in my garage which is kept at around 50 degrees this time of year. They were in egg cartons and propped up at a 45 degree angle. I turned them several times a day. I am reasonably sure of my rooster's fertility because I've found a few old nests of eggs and when I cracked them, there had been some serious development going on (even without warm temperatures or a broody hen!). I've never hatched eggs before. Could my buyer have candled them too early? Could I have done something different? I don't know anything anything about how they've been cared for since their sale, but would like to be certain I've done everything I could to ensure the eggs' viability.
