I have a broody serama sitting on half a dozen eggs for the last two weeks. Candled today when she snuck out to eat. Most look undeveloped but two look almost completely black inside. I can't see movement or veins but they are very small eggs. Are these eggs bad? Since they haven't been laying too long I expected a lower fertility rate but was really surprised to see so little success. I have some fertile serama egg in the incubator that I have already candled for development (7 out of 9 still good), should I leave them there or place them under my broody hen? They are on day 5. This is a new laying hen who went broody right after she started laying. She seems pretty determined though My batch of mail order incubated serama chicks didn't make it, ten of twenty didn't even try to develop, most of the rest early deaths, only two to lockdown- one died in shell never absorbed any yolk, the other internally pipped but never came out. These little birds are definitely tricky!
