I live in Western Virginia so can only answer for that store but they received them two weeks ago at the tractor supply in Appomattox County, Virginia.
You may want to give a call. Last week Appo TS was loaded with chicks. Monday they were pretty much sold out. And check the TS in Madison Heights and Bedford.
I know a gentleman selling R.I. Reds. Unsure on the Buffs and in close proximity to the Appomattox Tractor Supply if your search does not turn up.
