Agreed! I know E/E is extended black at this point, and things with lav generally stand for lavender, that's about it, but I can use it using the browse option and getting the color of chicken I want, and also I know how to properly save and name my chickens for later crosses. The chicken calc is how I learned that extended/dominant black is VERY dominant, like if u cross anything with pure black then their chicks are all pure black, it's only one or two generations down the road until u start getting something other than that usually..
