You wrote the eggs are from Silkie-cross hens or did I understand wrong and they are from hens of the breeds you named crossed with a Silkie purebred rooster?
I know a Copper Marans hen, Mathilda, her eggs are not extremely dark red so I wouldn't rule out CM involved regarding the darker brown egg. But sure could be RIR otherwise.
Some of my friend's crosses with blue egg-genes involved are laying (nearly) white eggs - so I think it's difficult about the light egg - could be with Cream legbar heritage or could be Light Sussex. ...Both eggs are difficult to assign in my opinion.
The eggs are kinda a mystery to me. Here's the link, maybe someone can notice\read something I didn't see.
