Hello, all! I am not yet the proud owner of any ducks, but seriously considering it. We have a small creek on our property which it teaming with toads and small fish. We had a heron that was visiting frequently, but we have not seen him at all this year. So, there doesn't seem to be any real predators to take care of the numbers... Is it safe to have the ducks eat these little critters? I don't know how they got started (they definitely swam down from the large lake up the street), but it seems odd that nothing wants to eat them. The creek is clean and the lady who owns the property with the lake is crazy about keeping things natural. So, I am sure that she is not putting anything weird in there. Thoughts?
