Mille fleur or plain old EE bantams?

[Aprilap55]

I bought these birds last year as Mille fleur cochin bantams. As soon as they laid , they brooded. I decided to let them sit on 15 eggs , all but 2 hatched and lost few due to chicks just dying for no apparent reason. I'm leaning towards trampling. Getting back on track , I'm curious if anyone can tell me if they are actually Mille fleur or just mutt chicks? I'm trying to sell them but I don't want to sell them as something they may not be. The lady I bought them from shows chickens and breeds various types including standard cochin and porcelain duccle. I have attached pics of chicks and parents. Any input is appreciated!

They look pure cochin, but some are mixed color.

Mixed color cochin bantams. Several appear to be partridge, but they probably have other genes as well considering the parents. The couple that are mottled could be called project color cochins.
