Our first hatch this year has a concerning bottom

[Hmore]

We had been given a dozen Fertile eggs and After about 8 days we noticed seven of the eggs weren’t developing so we removed them, on day 11 two started to stink and they had went bad for some reason. Now with 3 left in there today is day 22 and one hatched over night but something from it’s butt or maybe umbilical chord and some stuff seems to be hanging out.. it’s hasn’t been moving to much with its body but it does kick it’s feet when it peeps and its been crazy vocal for the past two hours, what is this and is it able to get better? Or should I expect to lose him... We’ve hatched eggs before but this is our first time since we moved 2 years ago and i don’t think I’ve seen this before

looks like he hatched to early. Was your temp 99.5. Or was it higher?

Hole where it absorbed the yoke didn't get closed up before hatch. Those are its guts hanging out. It's best to put it out of its misery now. It won't make it.

Looks like it could be the yolk sac, the chick hatched early before absorbing it all. Put it in a cup or a bowl to stop it dragging it around and to give it chance to absorb. There a few of these posts on today.
