Hi, I'm just wondering what mutation my new budgie is.
I agree it is a tricky one. Toni's answer is about what I would guess except that I think it would be greywing not clearwing. There is a small splash of colour high on her chest which could mean that her pied type could be double factor dominant pied or a combination of 2 pied types. Because of the dilute or greywing mutation it is hard to see what other mutations are thereits bit tricky... but i think skyblue, recessive pied, yellow face type 1 (YF1), and probably dilute or clearwing.
it will be interesting to see what others think.
