The unamed goose game
No not that.
My landlady bought two goslings. Spoilt them rotten, they grew up - and the male has turned into a right horror. Some visiting kids chased him and he turned savage.
When he started biting landlady, she just let him. In her words "He seemed to want to do it so I didn't want to stop him.". Left one arm black and blue.
Next day he had a go at me - I took him by the neck, told him he was a bad goose. A few repetitions of this and he is a reformed character (except he still attacks landlady's husband, just about draws blood from him).
I am now the 'goose whisperer'. The savage beast (was drawing blood from people), now pines for attention and follows me around. Doesn't attack landlady, will let her stroke him.
All I did was treat him the same way I would treat a dog that bit. Firm words and holding by the neck when behaving badly. Gentle voice for good behaviour.
