Hi there, so i’m not too sure if my bunnies are getting along with one another or not. Jack the eldest rabbit who is around two years old was neutered at about 8 months old and had a lot time spent in the house around us all the time, being handled etc so is very comfortable around me. My second rabbit Millie who is approximately 1 year old and NOT spayed just yet, had a different up bringing and not as much time spent around us and does not let anyone come near her or pick her up. They spend night times in the cage and day time out the back yard cage free.
When i walk up to them quietly they will be grooming one another in their hutch, but as soon as they see me, Jack will turn around and bite millie and chase her through the cage randomly. Or even when i just hang around them they will e grooming one another and Jack will ramdomly bite Millie and chase her out of the cage. I’m really confused with the behaviour and unsure what to do?
