Very cool project!!
It would be really efficient to somehow build it over the water where they just fall in the pond when they crawl out!!
I've built several of these. 2X6 frame with 1/4" wire mesh stapled to bottom 2X6, build a second box the same way with wire mesh on top, hinge the 2 and you have a "bone box".
4 legs on 2 floats. Works real well to throw road kill, rabbits I shoot, culled fish, etc.. Maggots fall through wire, it's a panfish feeding machine!
