I hope that your geese don't grow to hate chickens like mine. With all females it should not be as bad. I have a rooster who had to learn to back down. Boris gave him several floggings as well as biting his comb. Now when Boris honks the rooster asks how high.
They seem ok and friendly w them S long as the ducks are right beside them lol most don't even bother them . It's just the top hen who gets peckish - ESP at treat time .
