You're welcome ... And I doubt your geese are afraid of your drakes. Like I said, mine was a weird situation. 
I didn't put the geese into the huge community yard until they were already full-sized, but they were mentally still babies. My boss drake (tiny in comparison, an Indian runner) would start chasing them, and they would run from him, screaming their "Mama, help us!" cry. I would "rescue" them, and like as not, he'd do it again a few hours later. I'd pen him up for time-out, but it did no good. I'd fuss at him and hold him upside down in front of his girlfriends, and that would shame him into hiding for a day or so. Sometimes I got tired of it and penned him, but the rest of the ducks wouldn't range without him. 
It went on for many months until the geese FINALLY realized they were bigger. Or to be honest, until the ganders finally had hormones kick in and become aggressive enough back that they let each other alone. Once or twice it still would happen ... I'd hear frantic goose calls and look out to see that silly tiny drake chasing a full grown gander. 
Totally weird. I kinda doubt anyone else would say the same, but since it DID happen to me I didn't want to ignore the possibility. 
That drake attacked humans too. Acted just like a breeding gander, running up when your back was turned. Luckily his "bites" were pretty much just tickles. I think it made him furious that his attacks didn't scare us off and we would laugh at him.
