I have a flick of American Buffs. They have three nests going. One setup (natural setup they did this themselves) is one goose and TWO ganders! I was out changing water in the pools a few days ago and saw what I knew to be a gander breed the goose from behind. Yes, I saw his willy. Then, a couple days later, I saw what I supposed to be a goose in the trio ostensibly breed the goose. At that point I thought perhaps it was a dominant goose, but I saw them from behind today and saw HIS tool! I never thought this happened. There are three active nests and I do have young from last year. There shouldn’t be a shortage of females.
