These are nice males are these the Nelson Line? I have noticed over the years as cock birds they are just a little short in body for me and I would put more breeding pressure on length of body and maybe look hard on the female side for this length. You may one day next year see a female that after her molt may look just a little more Brick shaped than her sisters. Mate her and look for a long back male kind of like what Bobby produced this year. Then mate him back to his mother and see if his sons and daughters are longer in body. Takes about five years to do. I found when I did I kept my extended keels, the great brick shape but the tail angle drooped down to almost flat as ckls. It seems you always have a battle of something or you may get a perfect male in length ect and has a crappy comb and his brother will have a perfect comb and be short in body. Excellent birds and one of the top strains in the USA and a great one for the North and New England area. bob
