Another trick I have used in the past is to wire up the door for the first few nights so they get used to going in and getting a snack. Works well with trap shy fox.
And with Fox there is usually always a pair of them, one lookout and one raider. If you have ever heard three or four short yips when you open the door that was the lookout warning the other.
