I have been lining my "chick box" with newspaper and paper towels (for traction and less ink transfer). Lately my 1 and 2 week old chicks have been scratching the paper into shreds. I decided that perhaps I should use something besides paper and went with rice hulls at the reccommendation of the local feed store. When I put the babies onto the new floor material, they freaked out! I had to make sure the littlest weren't trampled as they all crowded onto the small piece of curved floor that was paper only. Now I've got them walking on the hulls but it appears they are eating them. Are they? They know what their food is--will they actually eat the hulls? Will this hurt them? THanks.
