I have barbado sheep and I think that one of my females is sick. She is a little over a year old. The reason that I think that she is sick because yesterday when I came home from work, I do like I always do and let the sheep out into the yard to graze more. Well, this sheep came to the fence but just stood there. She didn't follow the rest of the sheep as they went to graze. She continued to stand there with her head down as if she were grazing but she wasn't. She stood away from the rest of the sheep with little or no contact. After a while, she went back into the fenced yard and just stood there more. Her eyes look good, so I don't think it's worms. I did notice that she could possibly have a little diarrhea because her back side was a little "messy". Yesterday was the first day that she has exhibited this behavior. This is not her normal behavior. The only thing that I can think of that may be wrong is that maybe she got into some feed that she wasn't supposed to. She could have eaten some medicated starter/grower feed or she could have gotten into some bad hay that may not have been good or she could have eaten some of the chicken treats (bread) and the bread may have been molded. These are the only things that I can think of. I dont know if she has eaten or drank water because I was not home to see. I will notice today. If any of these are the reasons, what can I do to help here. Is there some kind of medication that I can give her? I'm at a lost and I don't know what to do. Any advice that you can give me would be helpful. Thanks This is a pic of my girl that is sick. *Edited to add a pic of my girl.
