I tried bonding them in the summer, after a few days they didn't fight and Dylan was licking wispa. I then extended their enclosure after three days (I think), everything went fine. After a week, they went down into the shed, in the hutch, which is in the shed. When I let them have the run of the shed, they started fighting again. Wispa, was the one that started the fights, think he wanted to be the dominant one. Sorry if this doesn't make much sense, posting from my phone. There is a thread on RU, somewhere, about their bond.
