Yellow-crowned BEC Kakarikis

[Kinny]

I'm curious as to if anyone knows how common Yellow-crowned BlackEyedClear Kakarikis are? I used to own 3, 1 died from a brain cyst bursting giving him brain damage (my poor Muta boy), the Vets etc could not figure out how on earth Mutas brother died as he was a big healthy boy and was only with us for less than 12 hours in a clean hygienic disease free home, and the 3rd (Mutas mate Misa) died in a far too graphic of a way to post, but it invloves an intelligent cat.. When she died I was heartbroken as she was the closest thing I had to my Muta, and also because I believe YC BEC Kaks numbers are rather dear?

Any input would be great! ^^

They're not very common at all- at least from what I found out doing research... 6 months ago we brought home a yellow crowned kak and a Tucuman amazon, I rehomed the kak with a friend because the 2 were having aggression issues towards eachother.
