i've been hearing starter crows i think for about a week or so, not a ton, but they are about. Also, everyone seams to have a bald spot on their back, but that's been the way to about 2 weeks, I thought i had them in the brooder for too long.(no light on, just a smaller space). I'm not sure what i can do if they start fighting, I have no where else to put most of them. they were supposed to behave till i put most of them in the freezer lolha. So far watching them they seam copacetic, and i haven't seen mating, but then again half the time i don't see it in my other breeders, they just have bald heads haha. next egg i get i will crack, i can't tell the difference between their eggs and my other breeders.
