There are absolutely no quality differences between fresh and frozen turkeys.
Frozen turkeys are flash-frozen immediately after they are packaged to 0°F (-17°C) or less, and are kept frozen until they are purchased. Once thawed, the meat of a frozen turkey is virtually as fresh as the day it was packaged.
Fresh turkeys are chilled after packaging, rather than frozen. Because they require special handling and have a shorter shelf-life than frozen birds, fresh turkeys are often more expensive than their frozen counterparts.
Fresh turkeys should have a best before date on their packaging. If not, be sure to inquire where you purchased the turkey.
When deciding between a fresh or frozen turkey, choose the product that works best for you. Frozen turkeys can be purchased in advance, allowing consumers to take advantage of special sales and coupons. Fresh turkeys, conversely, do not require additional time for thawing.
