Cuckoo Mauve and Barred Columbian EE?

[ChelsisChooks]

I got these two hens in a trade. Both lay blue/green. I plan on breeding them to a Cream Crested Legbar Roo. I’m curious to know if anyone has thoughts on identifying their color and color pattern to help me determine whether sex Link babies are a possibility.

First 3 photos:
Pinky: cuckoo that appears to be a chocolate, mauve, lavender color.

Last 2 photos:
Olivia: I’m wondering if she carries both the Columbia gene and barred gene?


Thanks!
