Sorry about your little one. They aren't an easy critter to hatch, but you'll get great at it eventually!i opened most of it up, he had absorbed most the veins but not the yolk - how much sooner do you think i should intervene (for next time)?
also - thanks so much for your help
Right when you lockdown, give that egg a listen. I've had them pip internally on day 23, and others on day 26. I check every 12 hours after lockdown. That way, you get a feel for the timing. I do not poke an air hole until about 18 hours after pip. If you're worried, though, it can't hurt.
I really recommend reading that article. I did read it 5 times! Immensely helpful.
