Never heard of a jay taking up the cuckoo's method of rearing young.
Magpies are keen egg thieves though. My parent's lawn is full of holes where magpies have cached eggs they've stolen from the neighbours ducks. Perhaps your magpies brought a jay's egg back to their nest and lost it amongst their own?
