Uh yeah, their claws are meant for digging (up morsels of bugs) so if you WANT them to be a natural tiller, lettem at it!
My first summer I ambitiously and naively tried sowing deerplot seeds in a 10x8 corner next to the run. It was obliterated in 3 hours! They’s some very happy birds lol. Next I built a wireframe on the ground, it didn’t hold up to our other wildlife or my clumsiness. I now have doubled the run size with 4 more youngsters, two just started laying. They don’t want out, quite content to lounge around inside the run, playing…Squawkers. Lol
