Here we go....... first one has pipped but at wrong end - I removed the broken bits of shell and made hole in the membrane - beak is now sticking out and I can see it taking breaths so hoping it will make it.
I am in the uk so we don't have ameraucanas - I'm thinking cream legbar by the egg...
I'm on day 18 too and excited/nervous. I bought a tray of 30 'assorted eggs' at an auction, and am down to 6! 4 bluey green ones and two light brown ones. Not such a bargain really :(
Will be asking you all to guess the breed if any hatch....
