Did you have your ducks last year at garden time? We have a very large garden and sell our veggies at our road side market stand. They got through our fencing. They ravaged the garden. It was awful! I put up streamers from amazon...I put up CDs...I put up an owl...nothing kept them out! We lost soooo many crops!! They ate through the deer fence. Yep..ate through it! Our garden is two acres. Plus we are planting another acre of just pumpkins, and 1/2 of sunflowers. We can’t put real fenc around that much area...we’re not sure what we’re going to do. I’m just telling you this as a warning. It’s adorable now...because there are no crops for them to ruin...but your garden is small enough to put chickens wire around it...do it!!
I had the ducks around last year, and i bought some
really cheap plastic fencing in the internet to keep them away from the tomato and pepper plants. It worked well for a while, until Erpelchen grew heavy enough to drag down the fence and let the girls in… Even spanking did not make him stop

, had to strengthen the fence with more and more stakes.
Ducks and goats must have a common ancestor, i call it the Weedosaurus Rex, because both eat everything green from your garden:
Hairy cucumber and zucchini plants? Gone!
Mildly poisonous tomato plants? - Yummy!
Fruits with tough outer shells like Pumpkin or Watermelon? - Just be persistent and gone!
Toxic plants like potatoes, rhubarb and riccinus? - Duck's can't read, gone!
They even ate the large thistles in the pasture! Grass? - Boring! - We want some fresh staghorn sumach leaves with some poison ivy as desert. Our poop always look like diarrhea anyways, so all those toxins make no difference for us…
I'm still searching for a robust and nice-looking fence for the tomato and pepper plant area. Problem is it needs to be temporary because i want the ducks in there to prepare the ground and to clean out after harvest season for the Duck Thanksgiving:
