I had 4 guineas. One guinea got a string from somewhere wrapped around it's leg. We caught it, unwrapped and treated the little cut from the string. Since it was getting late we kept the guinea inside and released it in the morning. It ran right into the barn when released. However, when we got home from work it was no where to be found and we couldn't hear any yelling. I've seen our guineas behave awful toward other poultry I've treated and released back into the barn. I'm wondering if they refused to accept it back and chased it off. Thoughts?
