Yes, although for them I would actually buy a bag of chick feed if they aren't on it already as chicks really really should not be on layer feed at all. If you do give them some (don't give them much as they really need to be mostly eating their chick feed, moreso than the adults as they're still growing) make sure to provide chick grit or else they will get sick. Yhis goes for any food besides chick feed. if they eat anything besides chick feed they MUST have chick grit and it must specifically be chick grit, regular grit is too big for young chicks. Again, switch the chicks to chick feed immediately. Layer feed has way too much calcium and not enough other stuff for growing chicks. It's not just the protein that's the issue here
