Assuming they are not litter mates, it is possible they are going thru an adjustment period. I have some that sleep in corners(a favorite thing for asf's) others that all three sleep in the hut. Give them time, if they are not fighting it's a good thing.
well they have been eating and drinking, sooo i guess i'll just wait it out, maby they'll be buds eventually. your right though, no fights to date but they have only been here for 24 hours.....lol
