The top pen is about 3 months old. The bottom pen more like 10 weeks. Top pen is Columbian, Partridge, Silver Penciled, Black and one project cross bird at the bottom left. Bottom pen also has some Golden Laced in there as well- this picture only caught about half the birds in that pen. I should have a lot more Columbians than I do but I was trying to use a sterile bird for breeding and it took me a while to figure out that it wasn't just a poor trim job that was causing the infertile eggs. I put a nice Cockerel in and now I have some decent ones developing.
Thanks Craig, this will be a great help.
