We have 2 six month old neutered bucks. They have their own room and we go in to spend time with them in the evenings. They know I will always bring them fresh veggies in the evening. They have starting nipping at my husbands clothes and getting his skin with it. Not sure if they are asking for more or grooming him, but I was hoping someone had some ideas to get them to stop. It makes him not want to spend time in there . I've tried thumping but it only stops them for a moment. Advice?
