I currently have my 3 month olds on a medicated starter feed. What do I go to next? My local feed store only carries the Meedicated starter then he goes to a laying pellet. He also carries the scratch feed. I have adults seperate that get the laying pellets(available all day) and some scratch 1 (sometimes 2) a day. Also wondering if I can start feeding the 3 month olds scratch? Thanks for any help.
