Absolutely. Grower feed is just higher in protein and some other nutrients and lower in calcium (hence providing oyster shells on the side). I notice more benefits with grower than 16% layer.
2 options are give the whole flock an all flock feed or give everyone grower feed, have oyster shells on the side. I give my whole flock starter/grower feed year round with oyster shells on the side (the brand I use doesn’t have an all flock).
