Looks like a gander to me What happened to the other 2 if you don't mind me asking. have you thought of getting it a friend. Geese really do like the company of other geese.
This is my Toulouse I have no idea it's sex lol I've had it for about six years but had two others with it up until two years ago. Someone was laying eggs when there was three, but now that there's the one I haven't found eggs. Could other factors be causing it not to lay if it is indeed female? Or does that just mean it's make since it's not laying??
