It depends on your beliefs. For my family and friends, the animals are properly bled. With birds and animals such as goats and rabbits this means cutting the jugulars and letting the heart force the blood out. Goats are usually hung upside down so anything remaining will drain.
Genesis 9: 3 Every moving animal that is alive may serve as food for YOU. As in the case of green vegetation, I do give it all to YOU. 4 Only flesh with its soulits bloodYOU must not eat
Leviticus 17: 13 As for any man of the sons of Israel or some alien resident who is residing as an alien in YOUR midst who in hunting catches a wild beast or a fowl that may be eaten, he must in that case pour its blood out and cover it with dust. 14 For the soul of every sort of flesh is its blood by the soul in it. Consequently I said to the sons of Israel: YOU must not eat the blood of any sort of flesh, because the soul of every sort of flesh is its blood. Anyone eating it will be cut off.
