Are chickens known to get scared to death? I had a 1 year old silkie hen drop dead either last night or early this morning. No signs of illness or anything. I feel like it could have been a fear induced heart attack because we recently moved her and her pen mate to my grandmother's and she has a pitbull. But I want to know if that's something they do. I would do a necropsy but I'm too squeamish and and the local vet and animal shelter won't perform one because "it's just a chicken"
