Growing small grains

I germinated some bird seed for sprouts sometime in June. We happily juiced the sprouts but the plants still had the roots and stems living. I felt bad throwing them into compost, so I planted it in the corner of the bed. There were probably forty or so plants there, but some survived summer heat and neglect. Now I have a small grain harvest:

I'm not sure what kind of grain these are, as far as I remember the package listed wheat, millet and milo, possibly some others. But the experiment is worth the try. You might not produce enough grain to feed the family, but will have some to make artisan bread and have more free seeds for the next season. I am going to try to seed maybe forty square feet of grain next spring. I imagine they should be seeded in February, just like any other warm season vegetable.
