Morning Everyone! Day 20 today for my incubator eggs. Woke up to one already hatched this morning, and another hatched at 8:00. 8 more pipped.

I've done that too. Surprisingly the severely cracked egg I caused last hatch made it to lockdown, but pipped wrong end and drownedUgh, so mad at myself. I was turning eggs this morning and was removing the duck eggs to let them cool outside the incubator while I turned the others when my dry fingers slipped on the dry eggshell and a duck egg went flying into a silkie egg. The smaller egg is cracked very badly and I’ve already tossed it. The duck egg has what may or may not be a crack, it’s hard to tell. I will candle along with the rest tonight. I suspect the duck egg, along with many others, isn’t even fertile. The silkie was tough to read, fertile but maybe already a quitter. Today is only day 9 and those small eggs make such small chicks, it’s hard to tell if what’s there is good or not.
Don't give up on cracked eggs though! I have one zipping right now that cracked when my kiddo was messing with the bator. Since it was the small end of the egg I used ducktape to seal it, though nailpolish and melted wax (crayons, lol) also work to seal a crack. Hope you get more fertile, though light colored duck eggs you should be able to tell by now.
. I did candle the silkie eggs on day 7, and threw out 4 ( 3 obviously non fertile and 1 blood ring). So 8 silkie eggs left in the bator. I am concerned about all of them though...as hey we're all shipped eggs, and the air sacks all look strangeBeautiful little fluff balls!!!View attachment 1179422
Super happy with the hatch rates, especially considering at my altitude hatching a shipped dark-coated Marans egg has been near impossible. Yay!
