I processed one tom at 4 months that dressed 7 1/2 lbs. Three toms that were processed at 5 1/2 months were 12 1/2 lbs. (1) and 13 lbs. (2). Heritage tom turkeys typically dress 18 lbs. to 22 lbs. when they are a year old for me.How fast are your sweet grass before they reach a decent weight for processing?
