I have been switching mine to the pellet, I offer a dish of each, and am slowly feeding more pellet and less crumble, since switching to a pelleted all flock my feed consumption has dropped drastically, I think because they are not wasting the pellet like the could with the crumble, no spooning out, and I think they are consuming less and the sparrows can't eat the pellet like they could the crumble. Chickens don't like change, anything should be slowly.
