Dave, mine are lavender based, so maybe lavender columbian? I'm thinking there's a possibility that the rooster is mottled but it's so hard to tell since the lavender is so light already. The little pullet has kind of a tan/cream over the lavender - almost isabel coloring, but don't think that's the correct name for the color. Love love love my projects, lol! This one is in the third generation so I'm getting a bit antsy... still hatching whatever they lay in the hopes of hatching my 'million dollar' chicken, hahaha!
