Okay so I have about 18 chicks hatching on Saturday. A mix of olive and Easter eggers. Made the mistake of going to tractor supply for dog food today and stopping to look at the chicks. I bought four of the buff Orpington girls that came in yesterday. When I put newborns in with them Saturday should there be a problem? I know orpingtons may be a little bigger than mine already. But they should only be about 4 or 5 days apart and there will be a lot more of the newborns. Should I be too worried about them getting along?
