I wonder were the snails are... I never find any snail just empty shells. Maybe the chickens ate them all, maybe they got tired of the shells and decide to live outside without carrying their home on their backs... that makes 'em homeless now!
I find empty shells in my backyard every days, dozens of them. Everywhere, all sizes of shells but always the same type. My backyard looks like a shells cemetery!
