So as far as NaNa/nana/Nana what is Rudy? Does it only stand for/affect the neck area? So Rudy is NaNa with something else causing no other feathering? Hope the questionnaire isn't driving you nutsI am breeding towards NaNa, I do have several Nana for 2 reasons, I want size in my flock too, so if I get a larger bow tied girl who is also large size I keep her anyway since NaNa is the easiest to breed back in, and b/c I love variety so if I get a pretty feather color / pattern / dark fm skin who is also Nana I keep it again b/c it is easy to fix the Nana next generation once you get a cool color or pattern, or top knot or whatever you are going for. I only keep a NaNa male no matter what that way all offspring will have at least one Na.
I also got a set back in the NaNa last year when my great NaNas were killed the birds I had left who survived the attack were mostly Nana. (b/c they were broody moms in a different enclosure.)
