Thank you, Sir,

I found a quote online that said the same thing, that a deer would have about an ounce of blood for each pound of body weight. So a 160-pound deer would have about 5 quarts of blood (since there are 32 ounces in a quart). It sure looked like a lot more than that though. The arrow had blood all over it like it had passed through the vitals or another large body section, maybe a rear leg hit?
