trimming wing feathers on geese

Occasinally, the gander will fly. If he stays in, the goose won't go as far. Can I safely trim their wing feathers like chickens?

All birds can have their flight feathers trimmed with no danger to the bird.  Generally only one side needs to be trimmed.  For the greatest effectiveness, trim both the primary and secondary flight feathers.

Always only trim one side as it puts the bird off balance.  If you trim both sides, they get their balance back and may achieve flight despite trimming.  But probably not a goose.  I'm surprised a domestic goose can fly at all!

You're right, they can sometimes flap really hard and fly anyway, even with stubs.

I was surprised to see him fly too. My husband said he saw him fly a few days before, but I figured he just "caught air"! When I saw him, he started about 20' away, gained enough altitude to clear a cattle panel fence by about a foot, and glided gracefully about 20' away. He looked so proud. He never flew until the goose started laying. He is determined to stay with her.
