We got a Brown Chinese Goose last year. It was the last one for sale and we felt bad for it so we got it. At first we thought it was a female but now we're pretty sure it's a male. We let him free range all summer and fall, but now he started to get a little aggressive so we have him in a pen most of the time. He's friendly towards me and my oldest daughter but will be aggressive towards my youngest. If we were to get a mate for him, would it help on the aggressiveness? Would getting another goose be best or could we get a few ducks?
