I feed mine a 28% protein turkey or gamebird starter. They can survive on 23% protein but it isn't just about the protein. Because they have such high metabolic rates and rapid growth, they need the higher levels of lysine, methionine and niacin that is included in a quality turkey or gamebird starter. I do not know what those levels are in your emu feed so cannot say whether those levels will be high enough or not.only have 2 keets and the chick. rather then buy 50 lbs gamebird starter can i grind up emu feed? it' 23% protein. been doing this for chick starter the last few years, and works fine for them. feeding them that now but read 25% for keets is being off by 2% going be a problem??
