Today is day 18... lockdown... I have an eager baby in there.... now I have to wait until this baby is out to get the rest ready.... crazy little thing
I've had bantams hatch on day 19. Personally never a large fowl that early but I have heard of it. My first guess would maybe it was stored somewhere warm or partially incubated by a hen before collection. Got a bit of a jump on development however that happened. Also double check the dates. It can be really easy to error one day in either direction.WOW! Day 18 is super early!
Whatever the case I love seeing a nice zip like that! So satisfying when they just pop out like they should. Can't wait to see the rest of your hatch.
