I try to make a good guess for the ones that are pretty much unknown. I have also been looking at their site a lot lately trying to figure out what I wanted to get 'cause I'm limited to 6 plus about a dozen meat birds. I have two EEs and four RIRs the dogs killed one of each I did have eight.
The one with the gold around her neck might be a cream legbar I don't know for sure but she sorta has the coloring, they lay bluish eggs if it is. (meyer hatchery has some that look like her)
