Many years ago I had ISA Browns from Townline. they were my most productive egg layers. I think these pictures are of my ISA Browns. I have been breeding my own Sex-Links over the years too and have pictures of both and they look alike. I may have posted these pictures before.
Thanks for posting the pics. I have a notion to raise my own sex links in the future also. What parent stock do you use...? How's egg production with your own hybrids...
