I give my chicks from day one Showmaster Starter for the 1st 3 weeks along with terramycin in their water for the 1st 15 days to protect them from various disease. After the 1st 3 weeks of feeding instead of changing to Showmaster Finisher, i still keep on using the Starter but now i add cracked corn and oatmeal in the mix with the starter and it's been working great for me.
