How to keep male goose away from ducks eggs

[puddlesgirl]

I have 4 female silver apple yard ducks since last year, they've been laying 4 eggs total everyday no problem (except winter some less, of course). This spring I got a male American buff goose and a female Pekin duck, they're 3 months old now, we raised them together. We slowly integrate them to the original flock and they are all doing fine, still kinda keep themselves separate sometimes but nor the goose or the ducks are aggressive towards each other. They've been sleeping in the coop all together since almost a month now.
Recently all I can find are broken duck eggs due to the gander breaking them all. The ducks are not laying 4 eggs everyday but maybe just 2 or even none (that I can find).
Is there any solution to keep him away from the eggs inside the coop? I would rather not keeping him by himself all the time because of this problem.
Any advice would be appreciated, thank you!

It seems the only viable solution would be to separate him from the ducks. This may become necessary when he starts trying to breed them.

I would strongly encourage you to get a female goose for him.
