I have 2 toulouse geese.... is there anyway to tell if they are male or female w/o having them sexed? They are both loud... their bodies are built a bit differently... one is a lot more stocky and has been since it was little and has a white tip on its beak. The other is darker and a black tip in it's beak. They are both loud and hiss (not at me though... at the dog when it walks by then with toys).
