After a quick search on the internet, I found this great article on Mail Online about a New York Chef trying the 12-bird mammoth. It can feed 125 people and has 50,000 calories. 3,500 calories makes one pound of weight in a human being. If you eat the entire thing, you would gain 14 pounds overnight.
The chef commented that the roast had powerful and gamey flavours and it was difficult to distinguish flavours from each bird. He suggested that the best result can be achieved by simply taking the four most distinctive tasting birds - goose, Aylesbury duck, turkey, and pheasant or partridge.
Man, even typing up this post makes me hungry.
