I am very fortunate to live in the same area as Dr. Whiting and his hatchery, so was able to get nearly all of my stock directly from Dr. Whiting's hatchery this past summer. We have ~160 of his birds, 50 of which are Whiting True Blues. I love them - they are a funny, motley crew of mixed colors, beards/no beards, and single/pea combs. They have a really wide range of personalities. I have a few that are pretty flighty (two are almost untouchable), but most are quite friendly. Many of them became really friendly when they came into lay. I have one WTB hen, the aptly named Cuddles, who is the friendliest hen I've ever seen. She will run from across the yard to jump in anyone's lap who sits down (and snuggle in for a nap).
They definitely have a few different breeds in their genetics, but they breed true for blue to blue/green eggs. I've been really pleased with my egg colors; important for us because we are marketing our Rainbow Dozens. The blue eggs in my avatar are from the WTB. Here's a pic of a nice blue WTB egg next to one of the Welsummer and Whiting greens, another specialty of Dr. Whiting's.

So far, the eggs have been small to medium but they are rapidly increasing in size, and should reach a medium to large consistently. They are a lot better layers than my original EE hens were at this age.
My birds were sexed but I did end up with three very beautiful roos. They aren't particularly friendly, but no aggression issues, they don't fight each other, and they do a really wonderful job watching out for the many hawks we have here.
I believe McMurray stocks WTB - not sure of their quality or consistency vs getting them direct from the source.
Here's one of our young roos, Rico Suave.
