It's the concentrated stuff I believe. He gets in the big jugs with squirt wand. He soaks the stump, & ground where the roots are for a few minutes, then moves to the next.
I've told once he doesn't need to drown them.
I have 3 large coops, occasionally I'll let one flock out for alittle bit to snack on grass, & bugs.
I would love to start free ranging sometime, or keep a Semi-Feral flock to cut back on bugs, or possibly both.(We have 10 Acres)
Part of the reason I don't free range, is my dad keeps dropping...
