My BO lays a cream egg and the BR's is a light brown.
The chicken guy at my local feed store doesn't recommend layer feed. Says he can sell me 50 lbs of oyster shell for $6, but I'd be paying premium price for the same (ground up) oyster shell in the layer food. More bang for the buck that way.
ACW, what type of dog food are you using? I thought about soaking some dry kibble for a supplement, but haven't tried it yet.
