We bought these two Chinese geese as a breeding pair in February. The breeder named them Agnes and Magnus. They were about a year old then. We are starting to suspect that the goose is actually also a gander. The “goose” is the lighter coloured one, who is also a bit smaller. Since we got them, the lighter coloured one’s knob has grown. It is also extremely aggressive and does not show any interest in nesting (definitely hasn’t laid any eggs). They pal around together a lot, but they recently have started attacking us. They hang out at our front door to go after us as soon as we try to leave the house. So anyone more familiar with Chinese geese? Do we now just have two aggressive ganders on our hands?
