So as my geese get older I am thinking more and more that I have two boys and one girl. We thought we were purchasing 2 girls and 1 boy but they look completely different! These are he two that I think are male, they look pretty much alike. I just realized this is the only picture I have of her....she is the one in the back I know you can not see her really well. But she has practically no knob and a thick white ring around her nose. I will try and get a better picture tonight. But any thoughts would be great.
