I have four 9 week old white turkeys. When I went down to water them today, one was dead. When I picked it up, I moved feathers around and noticed what looked to be bloody diarrhea. Also, when I picked it up by the legs, fluid ran out of its mouth (sort of white-ish). This is my first time raising turkeys. I have raised layers and CX's but have never had anything like this happen. Any thoughts on what killed it and how I can protect my other birds?
