Thanks for posting these pics. I scoured the internet searching for info on chicken/quail hybrids. I even thought that they might be able to breed naturally with bantams which led me to seramas which led me to the fact that they are expensive and hard to get haha.
But I thought it would be a really novel thing if you could have chicken sized eggs with quail egg coloration. That was really my only reason for the interest in the hybrids. If you could get one chicken to carry that gene pass it on to some more chickens and bob's your uncle new colored eggs for everyone!
