Most people will tell you that and a lot of breeders do that. I have been breeding them for several years with stock from 3 different breeders and have not introduced tailed birds into my program. A lot of it has to do with selection of the birds for your program but since I do not care to show then I breed what I like and only as many as I want to keep for myself. This year I have not hatched many as I just hate to eat the extras when they are so very gorgeous.
Oh, and don't let anyone tell you the roos are not good eating either. They are just as good as my Cochins, Ameraucanas and Welsummers. I was told they were stringy. Boy, was that funny!
I can't figure out where the infertility problem would come from unless you keep breeding shorter and shorter backs. Since hens need length of back for all their internal organs to have room for plenty of eggs in size and amount throughout life you don't want a short backed bird.
I do not necessarily breed for tufts but often am very happy when I have them hatch out. Again, I breed them because I like them and am no longer producing mass amounts looking for that most excellent bird. I just want to keep my flock going so I can enjoy my kids every day. I love their personalities and pretty bodies. They make me happy when I open their tractor door and they fly up to me for greetings. The girls have such pretty faces, tufted or not.
This seems to be the most misunderstood breed I have ever worked with and I love my flock. I no longer sell mine since people do not understand what they are like and I think locals around here really did not understand how wonderful this bred can be.
I would show you photos but I lost a lot of my stuff with a computer crash last year and I have since taken down my page on my website because so many people kept asking about them. I probably have photos if I dig through the thousands I have on my Drivezilla but really do not have the time. I am sure others will be happy to show off their beautiful babies!
