We have used Mt. Healthy for our 4-H kids' birds for many many years and have always been pleased with them, both for the meat birds and the other types (bearing in mind that a hatchery bird is never going to be of the same quality as a bird purchased from a breeder.) But for 4-H they've been excellent. Good quality, and the meat birds are much better than those I ever got from Ideal.
They are friendly and curious, esp. the Barred Rocks. The Speckled Sussex are the most reserved, though I'm now spending extra time socializing them
