I planted one acre to RR corn, so I could help feed two calves, and my 25 chickens. In spite of hurting some of my corn, with some contaminated spraying equipment, earlier this year, my corn was looking good, and had really nice ears on it by milk stage. my corn is now in a soft dent stage, and waiting for the frost to kill it. Everything would be great, except about 2 weeks ago a swarm of brown birds ( look like blackbirds, except for the brown color) showed up and started to rip the shucks down and eat the corn on the stalk. I can't be there all day , everyday, to chase the swarm away. as of today I have about 50 to 60% loss of my crop, and that fiberglass owl on a pole does't even slow them down. What can I do next year to combat them?
