Clayton, I have only 4 hens and 2 cockerels at this time in Silver Penciled Rock. The reason for such low numbers is that I have searched high and low for several years looking for a breeder with stock that was as good or better in type than what I currently had, in order to increase vigor/introduce another bloodline. I simply have been unable to find anything that I felt would move my flock forward. While going through all the efforts I've gone through to find another good line, time slipped away from me...suddently I realized this past winter that my birds were almost past breeding age. Thus, I have closed my flock for this year and possibly next, and I have been incubating every egg that has been laid in a frantic effort to save my line... as I mentioned, I have some things in the works, and my hope is that within a few years, I'll be back on track. Learn from my mistake: don't allow your numbers of stock to dwindle!
