Well they're 5 wks. old now and will be move to the coop this week. When should I switch over to non-medicated grower feed? An idea I had was to either make a blend of the two, or fill the the feeder starting with the starter feed half way and then add the grower feed on top. It would probably take 6 chicks a week or to to get to the starter feed on top. Any thoughts on this?
