Yea but any animal that is dead doesn't really bleed that well I figured its because it doesn't want to vs there's not much left , iv killed 5 lambs the last 5 days ..& 1 deer (but didn't cut the deers throat ) when you cut there throat they bleed like cutting a high pressure hose I always move them a couple of times so the pool of blood doesn't soak the wool , cutting the throat of a dead animal seems like a bit of a non event , but im going do as @
Tahr suggested , get its rear end high , stick it & pump it ;)
