For New years hatch I hatched out 15...12 before midnight, and 3 a couple days later. No NN, but I didn't have any NN eggs in the incubator. Most NN eggs were coming out not naked just black and I didn't want a ton of just regular black chickens.
Here are the NY's chicks (new years eggs were...12/15 the extra 3 were 3/4
For my rooster's last act, these due I am guessing the 12th. (I had all the chicks I wanted from him.) I did slip in on NN egg, I am hoping to get one more NN. The tan one.
I plan on putting my older chicks in coop, sectioned off, and combining my 7chicks from the 9th of Dec, with the chicks hatched on the 21st. But not in the chicken coop yet.
Of the 7 chicks hatched on the 9th I have just 2 roosters. The NN is a girl.
