well, now someone else from the Cream Legbar thread has sent me a private message, he actually thinks she IS a pure CL and not a cross -- I of course know absolutely nothing about penedesencas, nor about any of the genetics behind the various traits (he noticed that Amelia has yellow shanks, which apparently penedesencas don't have) -- so i'm just going to keep an eye on her and see whether she ends up laying blue or olive eggs!
and Deann, if you see this -- if she turns out to be a CL after all, I certainly would want to pay for the extra one today, it's been such an odd mix-up!
