i purchased 2 african and 2 white chinese gosling from metzer farms.com the one african pulled all the fur around the one white chinese goslings neck. she is completely bold around her neck now. he tryed doing it to the others also. this gosling just seems so aggressive. i hold him and he is fine. i have seperated him from the rest since. i have watched him and i think there is something neurological wrong. he bobs his head with his beak or mouth open almost like he is catching bugs and he does it constantly. i have for alot of years raised older geese and purchased them as adults. i have no exsperience with goslings. my question is is this normal behavior? i am very worried
