good luck and enjoy! It's so much fun watching them hatch
my hatch ended with 19 babies. I know I was impatient but I was fairly certain the rest of the eggs were dead. I candled each one and did a float test to each. No movement, no sign of life. I very carefully and slowly pipped them, one at a time and checked each egg. Out of the 18 left, 4 made it full term. One was Mal positioned, one had pipped internally but never made it through the shell (I'm assuming it suffocated), one looked like it pipped through a blood vessel and bled out, and one had a severe cross beak and never had a chance of getting out. The rest were quitters at various stages.
@dheltzel as far as the shipped egg experiment goes, Marans did great! All of them had some form of developement. Only one was an early quitter and the other that didn't hatch was one of the unfortunate full term ones. The Rhodebars didn't do so well. They developed great until the last couple days. They all looked good at lockdown but all quit shortly after (all but 2). One hatched great, no problems and the one I had to help.
I was rather worried about this little guy but his little toes are straightening out, he seems to have found his balance and was even showing some interest in food already. The welsummers also didn't do well. Most developed at least some (2 died full term) but only one hatched. The CCL, one hatched great and super fast, the other quit somewhere around 16-17 days.
Overall, I'm thrilled with the babies I got

they are quite the enthusiastic bunch and are eating and drinking already. The little splash ameraucana is already starting to grow in the feathers on the tips of her wings!
lousy pic but I had to blow it up. She doesn't stand still long enough for a close up lol
