Hannaford
Hannaford wins in the price department, with the cheapest turkeys at $.69/lb. These turkeys are Hannaford's store brand, and at that cheap, I can't imagine they come from a happy place.
After the store brand, there's $.99/lb Shadybrook Farms turkeys, which are not free range and could come from several locations around the country. Their website's FAQ notes that their turkeys are growth-hormone and steroid free, as the USDA prevents the use of these in poultry.
Butterball turkeys are $1.29/lb at Hannaford, and a search of their website provided no information about how the turkeys were raised. But coming from Maryland, where the Eastern Shore is filled with Mountainaire, Perdue, and Allen's chicken farms, it's not a pretty sight (or smell).
The last and most expensive option at Hannaford is their natural and organic store brand, Nature's Place ($2.49/lb). I sometimes buy this option at Hannaford, but can't decide if their flowery prose really adds up to humanely treated animals or not. Hard to say unless you see it yourself (which they won't let you do, of course).
Whole Foods Market
The turkeys options at Whole Food Market are simple: brined ($2.99/lb) or not ($1.99/lb). The birds meet WFM's Farm Animal and Meat Quality Standards, which include no animal byproducts in turkey feed and no beak trimming.
Trader Joe's
The newest kid on the block is offering brined ($1.79) and Kosher turkeys ($2.29) for the holiday. Their TJ's brand turkeys are vegetarian fed, and receive no antibiotics, hormones, or artificial ingredients. Kosher turkeys are raised according to Kashrut, and does that make them automatically humanely raised and slaughtered? I'd love to hear from someone knowledgeable on the subject.
Rosemont Market
Turkeys at Rosemont are available to order (order soon!) and for pick up on Tuesday and Wednesday before the holiday. The two options are Maine-ly Poultry ($3.79/lb) and Serendipity Acres ($4.99/lb). Both are free-range, with the latter being pasture-fed.
So, from cheapest to most expensive:
1) Hannaford Brand ($.69/lb)
2) Shadybrook Farms ($.99/lb
3) Butterball ($.99/lb)
4) Trader Joe's, brined ($1.79/lb)
5) Whole Foods, not brined ($1.99/lb)
6) Trader Joe's, Kosher ($2.29/lb)
7) Nature's Place ($2.49/lb)
8) Whole Foods, brined ($2.99/lb)
9) Maine-ly Poultry ($3.79/lb)
10) Serendipity Acres ($4.99/lb)
So while I'd love to be ordering my turkey from Rosemont, the thought of a $75 turkey makes me want to cry. I will probably shoot for the middle of the price range, picking out a 12-15 pounder that wasn't factory farmed.
