If you packed them in plastic containers and filled said containers with water they should be good. If they are just frozen in plastic freezer bags with no water I would question the quality. I'm a cheapskate so I use empty plastic Folger's coffee containers. Cut the bird up, put the pieces in the Folger's container, fill with water, and pop them in the freezer. If I have too many stored in the freezer I thaw them out and pressure can the meat in quart jars. Canned in jars it lasts almost forever although at my place it goes quick.
