I will confess, I do a lot of mixing up of my Marans. Worst case scenario, Ill end up with layers to sell eating eggs, which I cant keep up with the demand anyway. I have 4 gorgeous wheaten marans hens that I hatched from Katy, none of which are laying at the moment, but I have cuckoos, blacks, and blues laying that are out with the Wheaten marans roo, so Im hatching those, just for fun. Its been really interesting playing with these genes. The oldest group, that is about 3 months old, is a group from the Wheaten marans roo/cuckoo marans hens, and they were sex linked, which was neat. Now as they are growing, they all look like black coppers, some with strawy looking copper, and others with correct looking copper. They will go into the laying herd. Im now hatching some wheaten marans roo/black and blue hens, and these are all ending up either black or blue.
Fun stuff. Dont forget the fun, people.
