Not sure why. Various sources say there's 8 to 16 ounces of meat on a squirrel.
Apparently in UK it takes 1.5 to 3 pounds of meat to make a quarter pounder.
I kill and eat a LOT of squirrels. A conservative guess is about 400-500 in the past 10 years. As you might guess, I’ve cooked them several ways, but the easiest and most efficient method is with a pressure cooker. I cook 5 gray squirrels for 35 minutes. After they cool, I pick meat for about 30 minutes and end up with just 2 and half cups of shredded boneless meat - about 1 lb of meat.
I’ve made shepherd’s pie, jerky, burgers, and chili, but my favorite way to eat it is with bbq sauce on good rolls or with just a fork. It is delicious. Tastes like chicken thigh meat, but not as greasy.
Squirrels will eat eggs, nestlings and fledglings. The reason has to do with a lack of protein in their diet or some other deficiency.
