Wow! That's very cool! My incubator barely holds 7 eggs, and the largest hatch I'v ever done was 6 eggs! You must have a pretty big flock.
I'm just curious, I just ordered 3 chicks from backyard chickens, and I'v got 3 chicks hatching, planning on putting them all in together, and they will all be 2 days apart, 3 will be vaccinated and the ones that hatch will not be, I use medicated chick starter food for the ones not vaccinated, but that won't be a problem with them all together like that from different places, and some not vaccinated and others are right? Sorry if that's confusing.
