I have had geese for over a decade. But I have 2 Buff African gandars, coming 2yr. They have 4 grey wives. No fighting (I have had some other birds start fighting and have to separated in the past in spring).. They have a very long night pen with 2 houses and they all like to stay together , until I let them out in pasture in day time. I have been watching for any sign of fighting ....none, but they are let out with a group of Saxony ducks. I noticed the less dominat gandar bowing his head and following a Saxony duck twice... I am wondering if he thinks she is 'the right color, like me' or if he was kinda chasing her off...or what. He wasn't getting too close, just sort of herding her with a bowed head staying about 6 ft or more away.... He was raised with two of the grey females so I didn't think it was an identity crisis ( like a runner drake that tried to breed a goose before!).. and the duck wasn't really that near the other geese, she was more off on her own, not near the other Saxony..... just strange... He didn't go after her and bite at her , like I have seen some smaller geese go after bigger drakes... but the sizing is so far off , I didn't really think he wanted to try to breed...?
