I ordered 50 lbs of white millet, but received flax seed. Can I feed this to the chicks/guineas??? Do I need to grind it up first? Do I need to keep it refrigerated? Should I not feed it?? What am I supposed to do with 50 pounds of flax seed???? (FYI - the company did credit me for the flax seed and is sending me the millet next week.) I have 9 guineas, 10 easter eggers, 10 plymouth rock, 10 light brahams, 10 leghorns, 11 silkies, 10 sex links and wanted to use the millet to help train my guineas (and to treat the chicks).
