I'm posting this for a friend. She was vaccinating her chickens for fowl pox and somehow spilled about half of the vaccine on the floor of her coop. She was in a hurry and had to leave, so she piled bedding (d.e., hay, and chicken poop) on top of the spill so the chickens wouldn't peck at it before she left. She's concerned since this is a live virus vaccine that she spilled IN THE COOP. Anyone have experience with this?
