good chilly morning,
it is OK to buy from a feed store.
like BigZ says, they prolly get their chicks directly from Sunnyside. Sunnyside delivers the chicks to the feed stores with their own vans. eliminating the treacherous trip with the usps ..
and you can hand pick the chicks you want. If you are good/lucky you could end up with all pullets.
often, by the time you get to the feed store, the chicks are several days old. thus almost eliminating the dangers of them dying like so many do during the first couple of days .
Sunnyside also has a program where you can order POL pullets through the feed store..
you order them in early spring and they are delivered in the fall..
ask the feed store about this.
or call Sunnyside..
I did it once and was very satisfied with the birds..
