How much to feed?

[Mary Slaughter]

I recently switched from lab blocks to a seed mix because the only lab block
I could find had too much protein and my boys were getting fat.  I just
don't know how much mix to give them since they eat all of the fatty seeds
first.  The nutrient balance in this mix is pretty close to that recommended
for 2 year olds, any suggestions on how much each guy should get a day?

Thanks!
