thank you that is reliving to hear! I just over worry because rabbits are such a mystery. That even experts can not give an exact answer on the way they do things ya know? either the answer is that it's either really good for them to act a certain way or really bad and there are the slightest differences to tell which it is. Does that make sense?Bucks shouldn't have a"chin" or a dewlap. I am guessing he may of needed the weightloss. if he had one.
