I got my Speckled Sussex from Mt. Healthy as well. And they got to me within a few hours too, but they are about $3 more dollars for each chick and they are the same quality.
Hello from Central PA as well! :frow - I don't know of any breeders of Speckled Sussex and Tractor Supply doesn't have them very often. Meyer Hatchery has sexed Speckled Sussex and their minimum number of chicks to ship is three. :)
