My buck has just come back from a five week stay at a friends. She had seven does that needed bred. She doesn't have much pasture, but seems to feed good. He has lost weight. I don't know if it is from changing his diet or from having so much fun. I am wondering if this change will cause worms to flare up? Should I worm him? He was wormed in the fall just before breeding season started. He is eating good and feels good, but wondered what you do after a buck comes home? It was only a 30 min. drive away.
