Sometimes having more than one female in the kitchen can be a problem,
but in my experience as long as they know the rules there should be little problem.
The best thing to do is to take one of them who has needed a spanking anyway, put her across your lap and spank her in front of the others. Once that's done I'm sure you'll find that this Thanksgiving will be absolutely wonderful.
And to be honest if the others act up throughout the day too then it will still be a wonderful Thanksgiving anyway! Right?
