I have 6 cuckoo Marans that are suppose to be pullets. We all know how that goes. I believe 2 are Roos! Anyone have an opinion? They are 5 weeks old now, will be 6 weeks on Wednesday. If I keep a Marans rooster and Breed to my Ameracuanas will they still make an olive egger, since he is a cuckoo Marans? Thanks for any and all responses.
