Alright, so I had a batch of eggs with a 1/9 hatch rate. Have had the poor little chickie all alone in the brooder for the last couple weeks. Pretty much right after it hatched though I started another batch, they're due in about a week, so current chick will be 3wks by the time they hatch (6/8 alive and kicking). Should the fresh chicks and the older chick get along alright, or should I brood the new ones separately for a week or so before adding to the main brooder?
