I purchased a Wal-Mart turkey to compare with a turkey that I had raised here on the farm. Here are the pictures I took, my bird is the one on the right.
Size and Dimensions
Wal-mart: 15.63 lbs. The Poultry Guy: 15.75 lbs.
I will write more later on the actual numbers, and the conclusions I drew from the experiment. Stay tuned!
