A friend told me that the best time to feed the ducks at a certain pond is during the Winter because they're not already full of what people are bringing them throughout the warmer months.
So we did.
One day when we went, Lucky was a little overwhelmed. As soon as the ducks saw we had food, they crowded around. And they're almost as big as Lucky.
Another day, we found a different strategy. Open up the side of the van and throw the food out from there. The ducks went right up to the van, but they didn't surround Lucky.
