As my post title states, my hen had a 1/2 eaten mouse that was killed by rat poison in her beak (the mouse's abdomen was ripped open, blue, and filled with dead maggots). I took it from her which was NOT easy! She did not want to let go of her prize. I have had rat poison bait in my bulkhead doorway for years. That always kept the mice from entering my home. I never thought that the chickens would find one of the poisoned mice. So now I am concerned. Will the chickens die if they eat a mouse that died from rat poison? If so why do the farm catalogs sell the stuff? Please let me know.
