I have 3 sebastopol geese. A 1 1/2 year old gander and 9 momth old goose and gander (vent sexed by vet). They have been a happy little family up until today. The goose has repeatedly cornered the older gander and bit,pulled out feathers and tortured him unmercifully. Normal? Am I dealing with a problem child or even a 3rd gander? She's in time out for now.
