If you still have your BBS Ameraucanas, you can always make green laying EE's from them with brown or dark brown layers. Most if not all of your options will give you the same results though - blue or black offspring, beard/muffs, and either blue or white legs. Only a few candidates would give a little more color, such as laced birds.
Well actually, My roo is a beautiful splash Blue Ameraucana, and I was thinking about pairing him with one of my BLRW, probably the hen I kept with a single comb (to prevent a walnut comb). Would the chicks potentially carry the lacing? I also have splash Marans and BCM for creating olive eggers.
