Hi, my three rats are around 8 months old. Their brothers and have been happily living together but recently one of them has become aggressive when free ranging. Its gotten progressively worse over the coarse of a few weeks to the point that as soon as someone else comes out he immediately goes for them. They then fight and the other rat runs back into the cage. They are fine once they're back in the cage! i'm going to try free ranging them in a different area to see if this helps but i'm hoping someone can help me workout why this has happened? or give me some advice?
