Yes, they will try. I've had a raccoon attack two ducks. The raccoon bit the back of the neck. Unlike most chickens which tend to be killed without a fight, both of the ducks got away with injured, possibly broken necks, but one died the same day and the other may not live.

Yes, even if a raccoon eats a poisoned mouse it could be killed.
