You should have no problems at all, they will chase, play and tussle with each other, which is normal behaviour for both sexes. The more attention you give them the quieter they will be.
My top tip: get them used with the trailer so it is not scary, feed them in it every so often and they will literally run into the back, this will save you a lot of hassle on the day they go away. I trailer-train mine from weaning, so it takes two minutes to load up on the abattoir trip.
