The problem with muscovies...

Forums:

... is that they like to perch on things. Especially my solar panels!

Clip there wings, it only takes 30 seconds a bird twice a year. The only reason not to is because there unprotected ducks that need to be able to fly for safety. If my ducks flew I don't think id ever see them again.

We did clip the wings on one of the males who was being naughty, but we like them to be able to get to safety in case of predator attacks. They seem much more predator-proof than the chickens so long as they can get up onto something out of reach.

The ducks in the photo are all young females who haven't started to lay eggs yet. They like being able to get away from the boys for a while! Most of the males are too heavy to fly, so they are pretty safe up there. We found last year that once they'd raised a clutch of ducklings they don't seem to want to fly away, though we have lost a couple of youngsters like that.

Maybe lowering the solar panel so that it is no longer a safe area.
Or keep the "naughty" male right under the solar panel so that they think twice about going above him.

Burra, maybe running a 'perimeter' of something like that big rectangular wire mesh around the panels, so it sticks up, but doesn't block the light, might put them off?
I wouldn't suggest anything pointy: I love muscovies, but think they're a bit...dim...and I can visualise them impaling themselves!
Aside from the damage from their claws, a couple of good shits could reduce your light down to nothing
