As I work on the car a lot, I have rags lying around. There are some in the backyard and the chickens get hold of them and move them all over the yard. ??? I wondered if they pick them up and look under, for the worms that seem to hide under them? There's a very old terry towel, and three regular mechanic's rags (not microfiber). Every day they are somewhere far distant from where they started. Any ideas what's going on? I never catch them at it. Maybe they get caught in their claws and it freaks them out and they race around until it falls off?
