Okay -- I spoke with Wade Jeane, Channing Grisham, AND Charles Logan today at the poultry show in Newnan. Here's the real scoop on the different lines, straight from the horses' mouths.
Wade had different breeding lines of black copper Marans. He called them Coop 1 (C1), Coop 2 (C2), and so on in order to keep them straight. That's all the numbers mean.
In 2007 (I think that's the right year -- maybe 2006?), a tornado went through his area. More than 100 of his birds were lost, and his property was damaged. Almost all of the C2 birds were lost in the storm. He ended up letting Charles Logan take most of the remaining birds, including the C1 birds.
Wade does have a brother. But his brother is named KELVIN, not Kevin as is usually reported. His brother Kelvin has nothing to do with the birds. The breeding has all been done by various combinations of Wade, Channing, and Charles.
And that's the story!
