Having your own eggs to test hatch with really rocks.
Hope you have it tweaked perfectly now! But you have all summer to tinker LOL. I'm laying plans now for tinkering after the last batch hatches...
I have a bator intruder - I found a stomped unhatched egg/chick in the turkey coop, they must have oopsed one. Well, I thought dead for sure, picked it up to see where it was at - thought they were about due to hatch, when he moved, bloody, squashed, ice cold, torn yolk, stomped rolled and tossed out and there he was still trying.
I brought him in dredged him in flour to stop the bleeding wrapped him in a hanky and stuffed him in with the eggs.
He's gonna be a royal mess to clean up later but four hours, maybe five now - he's still alive, I tied off the yolksack removed the remainder of egg and torn membranes and got some of his "breading" off, and he's still going. Tough lil spud. His name is officially STOMP if he survives. Since I never did learn the name of the guy in Godzilla pictures who always gets stomped to death first. And KFC has been done. I briefly considered tempura - egg yolk, flour... get it???
