My one older duck is a perfectly behaved lady that doesn’t destroy them. She may sample a tomato or 2 but she doesn’t strip plants. But I had the drakes using team work to pick pole beans... one would grab the corn stalk or leaf and pull as hard as he could, and the other 2 went to town once the beans were within reach.

they broke one of the smaller stalks and I guess they discovered it works to pull on them from there.

The most frustrating was my jersey pulling down my entire pea trellis though.

somehow stretching her scrawny neck over the electric fence and grabbing it. They all had a field day with that.
I put a short fence around the more worrisome plants, 2’ high with bamboo stakes and chicken wire. They can still pick through it but they can’t reach everything to strip it. Lol. And moved the electric fence back a foot or 2. Haha.
