Welcome to BYC. I don't see a BCM in the photos, but your blue bird *could* be an Ameraucana - can you get a photo that shows it looking up into the camera so we can see any facial feathering it has? Your lighter bird could be a splash marans, but I'm not entirely familiar with them so will leave that up to someone more familiar to confirm or rule out -- not entirely sure about the leg color fitting that.
