He could also be a Blue Andalusian. If he is, he might look similar to mine... Lol McMurray snuck one in on mine, and he's my favorite roo ever, for sure.
I still think it looks just like what is promised in Dr. Whitings birds, the blueish color being one of several possibilities. Looked like they were mostly white, blue, black, and Splash, so I'm still leaning towards the Whiting for his breed.
If he's any other breed that McMurray offers, it would have to be a Blue breed, and they have very few, so it should make guessing easier if need be.
Only time will tell, but here's a shot if Blue, just in case you want to compare to a Blue Andalusian. Blue is a splash, though, so his color was washed out as a chick; he was pretty much white when he hatched.
One thing we need to look at, is the comb. Blue is a single comb, where the Whitings are going to have pea combs. So, notice how Blue already has a comb at one week old. Watch the combs, those are going to be the next indicator of sex. Males will pop up a noticeable comb within 2-3 weeks from hatch, and they'll also be friendlier, more outgoing birds, not shy to be handled. They're "cocky" per se
Edit* Blue was actually 2 weeks old in the photo, oops
