Typically, depending on what the outbreak is, of course, they may have to be destroyed. It's not only that, because when activists enter those facilities, particularly on poultry farms and also with livestock, these animals are not used to them, so they get extremely excited. They are scared.
I have a very large duck farm near me that activists broke into, and hundreds of birds had to be put down because they—pardon me for lack of a better term—freaked out and injured themselves.
