Hello, I have two geese, They are whiteish greyish geese that are pretty much the same size and have always acted the same. However, I went in yesterday and one charged me. I looked in the coop and their was an egg. The one kept constant pressure on me and the other stayed behind. Is this an indication that one is a male? I have never seen one mount the other one. If one is a male and one is a female then I will let her sit on the eggs and try to hatch them. Thank you!
