Best way to introduce my new rats to my current rats?

  I just bought 4 4 week old male rats. So adorable. I had one of the new rats on my bed, and tamaki was on the bed. He sniffed the baby, then walked off. The bed isnt nuetral territory. I know you should keep them apart for a few weeks before you start introducing them, but i think the sooner they are introduced the better
I think you should keep them separate but maybe once everyday you should take them all out and let them play. If they seem to be getting along then you could keep them together. If you notice the adult attaching the smaller one, I would wait at least until he gets bigger.
Okay! Sounds like you got this pretty good! So I think you should have them spend more time together, say, by ... having them play games together maybe?
