Oh, just another observation. Not really close to a home situation, but I’ve seen plenty times chicks from day olds to ones I know are at least two weeks get mixed together at Tractor Supply (Farm supply store that sells chicks). Of course they are high volume, high stress, high turnover situations, but every time I look (and that’s a lot!) the mixed bins seem to be getting on fine together.
