I know I'm digging up a SUPER OLD thread, but unanswered questions drive me insane lol! The Quail In the 1st pic from the OP are a European mutation called "pansy". It's VERY similar to the red breasted mutation in Button Quail (cpq). To my knowledge, Not related to the Italian Mutation.
I can say with 100% certainty that the "Pansy" mutation of Coturnix is now In the states. ONE guy has them lol....luckily, my birds are directly related to the line that produced the Pansy mutation in the states! No more eating quail eggs at my house, I'm hatching every one I can, haha! I have some info and pictures but I don't have permission to post it, so it will remain in the vault for the time being.
