the green millet might be pretty good BUT once youngsters had fledged - i couldn't see any difference in health/fitness of the young.
did they like it YES! - is it a waste of money NOT SURE - i suppose it's like comparing junk food to quality food. if you were unaware junk food was not good for you - you'd be none the wiser.
i have sold about 2500 mini donuts in the last couple of weeks. we all know their junk food BUT it doesn't stop my customers eating them

anyway if things go really bad i can always throw away the donuts and eat the millet. when i come into breeding condition -watch out l,o.l.
