What can I plant or do to make better duck habitat before next year? I have access to 2 small tanks and a 3 acre pond.
1. Rain dance. If you've got water, you're ahead of the curve.
2. Food. Snag some aquatic vegetation (duckweed, smartweed, tooth up, etc) next time you're out and transplant it to see if it flourishes.
My bet would be duckweed/pondweed/hyacinth. If cows can get in the pond, hyacinth may get eaten.
