Note: I posted this on the other forum also.... My favorite hen has had so many loose stools lately that it has made a mess on the feathers on her bottom. Is there a general wormer that I can administer? Would it be available at a feed store? What is the best way to clean the feathers on her bum? She seems to be in a great deal of distress when I fuss with them. I considered wiping with warm water, but I thought I'd better wait until the freezing temps went up a bit.
