Not a lot, but I have come to really like them. They are game. By luck I acquired a pair. I was told they were bred by the Flowers family and they liked them dark, although my interest in them was the Blues they would throw. The females come in in the low 2 pounds and the cocks are in the upper 2's. The little guy in the picture is probably around 2:8, although I have not weighed him in a while. Pretty nice to handle although not as quite as SDM's Blues.
I posted some earlier pics and the are deceptively solid little birds. The pic of the stag on the roost is a little longer in the leg, which I think gives him more of an American look. What do you think? I couldn't get a good pick of him standing tall and alert though.
