The EASIEST way would be to have him give you the female until she lays... if he is concerned and is wanting the best for her and the eggs, then this makes the most sense.
Put her in QT. Once she lays either you get her back on feed, or he comes and picks her up.
If he is only a few minutes away then arranging transport of a snake will be easier then trying to move eggs.
He needs to be responsible in this and accept that there are certain limitations.
