For now I cleaned a tub put new bedding and sprayed little cologn for a different scent. Then I added the male than each femae one at a time. I havnt seen any fighting but the male is in one corner and the females are in another. I put the weanlings 1.4 and the 4 subadult females together so the male can grow up with them. They are all huddled together so i dnt think there will be a problem
