I know someone I trust in McKinney who breeds pure cream legbar and French blue/splash and black copper Marans. I sent her a message to see if she has pullets old enough to go in with the mature birds for sale. If she does, I'll pm you to give you her contact info. Also, I work in Garland, and will be happy to relay the birds to you if that's your style of purchasing. She is not far from where I live. I think she has F2 Olive Eggers which would be marans roo over cream legbar. Anyway, I will let you know.
I have ameraucanas/auracana mixes, but they are only 6 weeks old and won't be ready for the big coop for another few weeks or so....
