I finally let my guineas out to free range. There are only three of them and I had one female. I walked outside in the morning since I heard them making a ridiculous racket (like more than usual!) and my dog (german shepherd mix) was running uncontrollably back and forth at them. Just running at them and after they flew up she ran away, back and forth. She was really out of control I had to grab her and put her in her kennel. We have had chickens as long as we have had her, she always tries to herd them but never touches a feather.( The only time we have ever had a predator problem since we got her was a loose dog since she doesn't view tame dogs as predators and the dog ran off with one of our free-range chickens.) I walked around the corner and there where feathers everywhere, and no sign of the female guinea. My dog is in a wireless fence system so I walked her entire boundary and couldn't find anything. Today I finally found the body (it happened wed.) and it was in her boundary and it was mostly eaten, the softer parts that is. I called my dog over and she immidately cowered and layed down. And for the first time in a very long time I could not get her to come to me. She was obviously feeling very guilty. But I am trying to figure out why exactly she was acting that way.... I have always been told and have read that once a dog does that and tastes blood and the excitement they will keep doing it and won't stop. But she has not gone at or even looked at the guineas since. And I just don't see her eating it, she is well fed and I have been told dogs usually only do things like this for sport, which would be her reason. When I found her that morning she had no evidence on her that she had just attacked one of them just the chasing them. So there are some factors that make me think it wasn't her, what do you guys think??
