These blue jubilees were created right here on the farm. So, they are unrelated to any others that are selling blue jubilees at this time. I have only sold a handful of chicks so this is a rare opportunity to get an unrelated pullet. She is an F5 or fifth generation pullet. I have used birds from Greenfire, Sacre, Fancy Chick, Thistledown Farms, Korfus Kluckers, and Daniel Velasquez in the creation of these blue jubilees. It's very possible there are some other sources as I have used multiple lines for the blues and the jubilees. I am currently running 3 pens of blue jubilee/jubilee orps and have outcrossed all my blue jubilees to unrelated jubilee lines for excellent diversity in these birds. If you do not have blue jubilees, you can breed this pullet to regular jubilees to hatch 50% jubilee and 50% blue jubilee.
