Meilah 2:1

The laws of misappropriation apply to a bird sin offering from the time that it’s consecrated. After the head has been nipped, it can be rendered unfit by a t’vul yom (a person who immersed by day and is awaiting nightfall to complete his purification), by a person who must still bring an offering to effect atonement, or by being left overnight. Once the blood has been sprinkled, the laws of piggul, nosar and ritual impurity apply while those of misappropriation don’t.

Meilah 2:2

The laws of misappropriation apply to a bird burnt offering from the time that it’s consecrated. After the head has been nipped, it can be rendered unfit by a t’vul yom, by one who must still bring an offering to effect atonement, or by being left overnight. Once the blood has been drained, the laws of piggul, nosar and ritual impurity apply, and misappropriation applies until it is taken to the place of ashes.
