i know my het pied are proven (3 pieds) over the 3 clutches she laid ( 1 clutch was slug my fault as I had a poor diet going at the time) but the other 2 clutch s were all great and I have kept the one male for next season to use back to his dame so I can increase the odds, for a higher white female( I hope) I remember paying around 800 for my pair about 7-8 years ago. I also purchased them from 2 different breeders in 2 different states.
