how early?

[natchlaly]

Was just wondering what is the earliest anyone has had chicken eggs pip/hatch? my eggs seem very full with air cell and a couple of mm above it visible rest of the egg completely black and they are only day 16/17

 

[can you hear me now?]

sometimes they hatch a little early depends on how long they sat before they were hatched. I know i have had them hatch at day 19 or so from incubation, but it was pretty warm in my house and i had them waiting for other eggs to go in with them.
