Have to be careful with goats, they can bloat with certain things and some plants are poisonous to them (like azaleas) so they can’t eat just anything. Fortunately, well fed goats tend not to eat stuff they shouldn’t though.
Anyway, I’m thinking of fencing off a section of pasture this year and planting field corn, millet, oats, barley, rice and soybean and see what happens.
I have a solar powered portable fence that I can use to move my goats to non fenced areas, plus a neighbor with 6 acres that has already offered to let my goats graze if I fix her fences.
Good luck keeping your goats contained with electric fence….
A friend bought a goat to help clear a small plot. He imagined eating it once the job was done, but his girl named it. He wound up chaining it to his outbuilding and the goat head butted the small shed to the ground!
You can plant it after the other grains have finished and my chickens enjoy it when mixed in with their weevil infested cracked red wheat.
Throw in some greens and cow bones for them to peck at and you will have happy chickens.
