This is my son's 4-H project and we trusted the TSC guy who gave us the Dumor Starter Feed of 20%. Just read that our chicks should be eating 24%. I don't know where to get it (Btwn Cincinnati and Dayton OH) or if I need to bother at this point? They are growing. One appears to have weak legs - stands to eat & drink but just sits or crawls a lot. Others are approx 10-13 oz. One teeny one is 8 oz. Please help - I'm such a newbie!
