Chick with crest?

Yes, a number of breeds get crests; none of which happen to be the ones you listed.

So something else is mixed in.

Your chick looks to have a crest similar to a Cream Crested Legbar, and may have some of that mixed in, possible the Marans to create an Olive Egger, but the legs (hard to see) almost look willow so I would normally say an EE...but CCL is already a blue egg layer and wouldn't normally be bred back to an Ameraucana to produce an EE unless I suppose someone really wanted to experiment with blue egg colors.

Or you could have a mixed breed bird with another crested type....often Silkie mixes will have a bit of crazy crest like that, and with the very black beak, it is possible it is a Silkie mix though the feathering is natural feathering (vs. Silkie "hair like" feathers).

So it is likely a mix...and not from any of the breeds listed as none of those would produce a crest.

Unless you are in Australia or Europe....

Araucana standards there allow for crested and tailed Araucanas with willow legs, but it should be muffed/bearded as well.

And UK standards allow for a crested Ameraucana, but again they should have beards/muffs.

You might then have a European standard Ameraucana/any other breed EE which kept the crest but lost the beard/muff in the hybrid.

My thought then...Marans/Legbar to create an Olive Egger.

I agree.
