i cannot believe the bad luck with this clutch! A couple days after the first cracked egg, i checked under the broodies to make sure there were not any others. One slipped from my hand and cracked.

Luckily, upon candling, there was no chick inside.
Then this morning i checked and saw one broody off the nest, and another hen had crawled in the nest. i found two extra eggs had been laid in the nest. Then saw one of the hatching eggs laying the coop floor, with a crack in it! It was not totally cold, but cool. Upon candling, i found it does have a chick inside - alive or not, i don't know. We are on Day 18 here.
Anyhow, my husband helped me seal the crack with wax. It was not weeping at all. i have it in the incubator, which is coming up to temp pretty quickly. He suggested, and i agreed, that once we have a stable temperature, to take the rest of the eggs away from the broodies and just incubate them the rest of the way.
It's very disappointing. i had hoped to see little silkie chick heads popping out from under mom's feathers. But i just don't want to take anymore chances.
If i get the urge to buy anymore hatching eggs, will someone please smack me?
