Just got back from a run to Caledonia Farm in Barre, MA. I picked up 20 broilers and left behind an order for beef brisket. They also have eggs, but they'd sold out that morning at the farmers market.
The broilers are spectacular - 6-8 lbs, flash-frozen. The farm is pesticide free, sustainable style (eatwild.com is where I found them). I got way too much chicken, frankly. Expected them to be smaller. Now I've got an entire freezer stacked full and *taped shut* to keep the chickens inside and several more on ice outside the freezer until my friends all arrive back home to surprise chickens tomorrow.
Check 'em out at http://www.caledoniafarm.com/ - you can go out to Barre and pick up regularly, or you can place an order and wait til the next Boston delivery date in October...the owner is a nice guy and it's a lovely, if somewhat long, drive out there, with lots of farm stands along the way (got some amazing cherries and strawberries).
