H how large must plants be for duck and goose pest Management

So I have a very large area that I can garden in that has my ducks and geese living in it previously and goats running then pigs for a little bit and now it is nicely tilled up. As a fairly secure 5 ft tall fence and so far nothing has gotten to the ducks or geese which around here is a miracle. So how large do various plants need to be before I can transplant them into this future garden. I did direct those some onions and potatoes and they're doing really good but I think other things the geese and ducks would find more edible. I do want to direct those some corn and a few other things that do better without being transplanted but I'm afraid that the weed eaters will eat them.

In my experience, the issue with ducks at least it's trampling damage. So, big enough that a duck would rather go around than over the plant.

Geese, well, I don't have geese now, but when I was a kid they'd pick the berries off of the raspberry plants. I know there are specific breeds developed for weeding, but we just fenced them out of the garden areas. Sorry I can't get more helpful.

There are many different breeds of ducks and geese. Some do better than others in gardens. In general, they will trample or eat small plants and eat leafy greens, vegetables and fruits. Weeder ducks were developed for cotton and tobacco and older corn, none of which they like to eat, so the young weeds were tasty compared to the crop.

If your fowl are only protected by a five foot fence, it is only a matter of time before predators attack. They need secure housing or a livestock guardian dog 24/7, or both, depending on your predators.
