I volunteer at the Poultry Tent at our county fair. Yesterday was the day to bring our birds in. One man had a lot of pretty little bantams, little Dutches. Suddenly one of the other volunteers yells to me "Do you know how to clear an impacted crop?" I went to see and the little hen was already limp & lifeless. Her crop didn't feel too stuffed, but her beak & throat were filled with crumbles. The owner said it happened because he feeds his birds moistened crumbles & they weren't used to them dry. ???!?!?!?? His other birds were doing fine. This man has shown birds before at our Fair, I asked him "Why don't you get your birds used to dry crumbles if you know you're going to show them here?" My own bantams, & everyone else's birds, do well on dry crumbles, at home I feed dry pellets. What caused this hen to die? The dry food? Impacted crop? Was she too hungry & bolted the feed? What could have been done to remedy this if noticed in time?
