Is there way to make a status effect last only until the unit's next turn?

Well as far as I know atm, no...
However, Chicken do last until next active turn IF it isn't caused by faith <10.
A good start would be comparing Jump and chicken statuses...

Thanks. I looked. Jump and chicken, as well as defending for that matter, have completely different options checked. It may be that it is a hard-coded feature. I'll experiment and see what comes of it. =)
