Wow! So glad I found this thread. It's among the top listings when you search Google for "will my cracked egg hatch".
This is my first time incubating chicks. I've had chickens as a kid but this is the first time I'm raising them as an adult with MY kid. Since school is cancelled due to coronavirus, he never got the chance to do the egg hatching lesson the school had planned. So since we just moved into our forever house and my friend from the National Aviary was willing to help, we're hatching some chickens!
I've got Seramas (the ones I plan on keeping the most of), Silkies, Polish Crested, and some other mixed bantams that I won/bought on
eBay in batches of 12 or less. Of the 9 Seramas, only 3 were viable. 8/10 of the silkies are developing. And ALL 16 of the mixed Bantams from the wonderful guy I bought them from are doing well and looking good.
Of the 3 Seramas, 2 are micro eggs (the only 2 that came in that order) and the third is not much bigger. When candling the Serama eggs with my son, one of the micros slipped from my hand as I was pulling it out of the incubator and it had about. 5-6" drop onto my table with a tablecloth. The shell cracked lightly and spidered outward a little bit but the membrane isn't punctured and I can still see movement and development.
After reading through this, I took some candle wax and used the smallest amount possible to deal up the cracks. It's not a very big crack and it hasn't altered the shape of the egg itself, it's more like a hairline fracture than anything. But reading through this thread gives me home it'll survive!
It happened on day 10. It's day 12 and everything still looks good. We go into lockdown next week and I'm hoping and praying all 3 Seramas make it! Not that I don't care for and want the others to hatch, too, but I fell in love with those Seramas the moment I saw them!
I'll post an update on whether or not the little guy or gal makes it! Thanks for all your stories!
