I have five bunnies, I got three from the pet store and two from a local petting zoo that was selling the older rabbits. I bought these two bunnies that look only about a year or two old, and it was fine for a few weeks but then the male I got from the petting zoo was chasing the male I had gotten from the pet store. I thought at first the two bunnies were just playing or were fighting because they were both males but lately the bunny has been chasing even the females and it's not even a mating thing, he chases them and bites them and pulls out their fur. I was wondering if anyone could help me with this. Thank-you.
