I have a young babydoll that has made through a bout of pneumonia with help from the vet. Now that he is getting stronger, (still not at 100%) I’m placing him back with his sheep friends, but he is preferring to walk off and be in his own space just standing around. He’s about 4 months old, very small and doesn’t seem to want to “sheep.” I’m not a real farmer who can handle the thought of culling, any advice on getting him to be more interested in his flock?
