I purchased several bags of game bird starter. It's 28% protein and I fed it to a few chics, they are growing much faster than the ones on normal 20%. Is there a problem with 28% that I'm not seeing? The bags I purchased were only $20/6 50Lb bags(The feed store was going out of bus.). I first thought that I would mix it with regular feed but the results I'm seeing are great. The chics are bigger and much more active than the normal chic starter.
