Menachot 78 - Offerings Coming with Bread
Usually, an animal becomes an offering when the owner designates it as such, and then it cannot be used for any other purpose. The breads that accompany a thanksgiving offering becomes sanctified not by owner's declaration, but by the slaughter of the animal. Thus, if he slaughtered the animal while the breads were outside the Courtyard, the bread did not become sanctified. Likewise, if the breads were still baking when he slaughtered the offering and their surface did not crust, or even of all the loaves crusted except one, the bread did not become sanctified.
