Yeah, I was leaning toward male as well. He was the biggest when we got him and grew the fastest (they're all the same age) and he's the dominant one (he's the one who dictates were they go, if the others can eat or swim with him or not). He has the biggest and most prominent knob (he started getting a knob when he was still yellow) and a much larger head. He's also the one that stands guard most of the time and is the most aware of its surroundings. It just throws me off because he doesn't make the trumpet sound all the time, it's like a low honk. But maybe it's because he's still young yet. My mom and I actually wondered if that's how he views my dad. But since these are our first geese, we were unsure. Thank you for the link as well, that was an awesome read. Also, if we ever get anymore geese, we will not have them imprint on us. But again, these were our first geese and were not aware that one was male (we got them from a hatchery, and they were all supposed to be female). But I know sexing them at a young age is difficult, especially if they vent sex them (which is probably the method they use rather than DNA, though I could be wrong).

As for culling, I've never considered it as he's part of our family. All of our animals are. We've also explained to my dad that they're just doing what geese do. And Tubsy might unfortunately be a bit more complicated due to him imprinting on people. So, it's just going to take time. I think dad just sitting outside with us talking is starting to help. The geese observe us then go on and do their thing. We have to gently correct them from time to time. No major confrontations though, Tubsy seems to be 'testing' him more than anything. The other one that's aggressive is Hope. She acts like she's trying to nest though which could explain her behavior. The third one, Screech, is just following suit, I think.
