5 month old pullet and a duke dog proof?

Found a lil coon sign around my chicken coop this evening. All my live traps seem to have sprouted legs and walked off. Just set a couple duke dog proofs right at dark. And I got to thinking, it would be pretty a close as as to weather a 3/4 grown chicken could fire that trap. All the chickens are locked up till I turn em loose but anyone have any experience with this?

You should be fine with the Dukes, as they're only a pull-type
trigger...unless they've been modded.
Stockers...all good. They'll never be able to to trip them with
those springs.
If nervous, snap when you let the lil ones out. Then no worries.
Or cover with bucket/coffee can.
