I can't for the life of me figure out if my youngest goose is a goose or a gander? It's about 2 months old now....I tried vent sexing it when I recieved it about a month ago and I thought it was a girl? I've been pretty accurate at venting my ducks but this one had me stumped as I never vented a goose before lol They are both American Buff. I read that when they walk with their heads straight up its a gander....this one does this sometimes.
