So I am going to a friends farm (Linda Zeagler) to pick up some mandarins and talked her out of a few of her fantails. However, I am not too experienced in the pigeon department and neither is Linda. So I looked it up via Bing. I found several wive's tale versions and a couple that I know to be fairly true like their stance but hers kind of come and go as they please and I probably wont exactly have time or a really good look at them relaxed. So what are some definative sexing techniques I could use?
