Odd question, but the park where I feed ducks and geese is teeming with fire ants. I always get zapped once or twice and the last time I visited, I noticed the birds shaking their bills after eating scratch that was on the ground. Since they shouldn't have to choose btwn eating and being bit by fire ants, I thought if I had a compact, mobile feeding trough we could all get bit a bit less. Any suggestions for making one (or would it just be better to buy something?) Thanks so much!
