I don't think she has chicken muffs. I'm a little concerned now though as we have a pool and have begun cleaning it. We use a sand filter and pump the backwash out into the paddock, which contains chlorine in the water and of course this brings the worms to the surface. I suspect the chickens have eaten some worms today as they don't quite seem themselves. Usually when we get home from work they are hangin for some bread but today they didn't seem all that interested. Could this be cause for any real concern? Any help here would be greatly appreciated.
