I just picked up 2 light blue hooded female dumbos and a male American Blue dumbo all breeding size. Also i found a younger female Rex blue dumbo that is probably only 5 weeks old, so i will have to wait for her. My question is what will happen if i start mixing these traits? I have a full grown Siamese dumbo male that i can mate to the girls including the blue male. Is it possible to put both males with the females and get a mix of both genes in the babies? Also is Rex a recessive trait or what does it fall under?
