Situation normal
They are worked on average only once or twice a week. One of them, four to five times a week. None of them are competing at the moment. One has a foal at foot.
In that case - chuck them out, with the exception of the mare and foal (which you need to play it by ear with) and the one that's in full work.
Inform your owners that is what you'll be doing, with a weeks notice.
