Pretty cool, I'll have to give them some healthy treats then! Already going to give them alfalfa sprouts. Been saving pasta sauce jars forever, finally have a use for them.
Not a good idea to mix them until they're all 6-8 weeks and adults...even then there can be dominance issues. Can be fatal. Maybe try to find someone with chicks so she has a friend? Not sure how well a single chick will do.
