I would call them long fin, I haven't seen a ram like this before.. But I haven't seen everything, the tail is also long and flowing kind of jagged not just extended top and bottom..
The eggs made it through the night with none fungusing.. So thats a good start..
I believe that is how it goes too Livingart, if they get a random colour or trait they inbreed the crap out of them until it gets pure, thats got to make them somewhat weaker.. I also managed to get some awesome cockatoo's off a very good local breeder who crossed them back to wild they're colouring up nicely so hoping they are pretty hardy
