hi I have 2 pekin ducks, I'd love to take them for a walk, can you get harnesses of some sort, they cant fly but wouldn't want them running into trouble

We take our goslings for walks in the fields but then they are always inside an enclosure and they follow us, its funny to watch lol. Ducks are similar, you could try adapting a dog harness, but careful you don't strangel them or panic them. Why do you think they can't fly? Our Pekins fly up to high perches!

these 2 flap their wings but dont get very high or far xx

Have you taught them to fly? The kids used to run along infront of the ducks or geese etc and flap and they birds would follow and eventually get off the ground lol.
