Why not grow some in a seed tray, seed tray, kitchen roll sheet on the bottom water too make moist, mixed fresh corn spread on the on the surface, propagator lid, watch for shoots, remove the lid, keep moist until it reaches the desired height, lift out, pull paper off the roots, feed to your birds, you can give them sections of the growth, but keep the remaining moist, for succession planting, add new seed to another tray before the other is used.
GM seed will not sprout, best to get organic.
