Hi! Welcome to BYC! That's a rough start!!! I only ever hatched out one chick. The other 12 in the incubator never developed. And guess what? It's a boy!!! I understand the desire to incubate, but if I were trying to increase my hen population, I'd buy pullets at this point. Good luck with all your chicken endeavors!! We're happy you are here!
It sounds like you started off with a challenge with all the boys in your hatch! If you have questions or just want to share your experiences, feel free!
