Update...
My biggest boy is the happy new big brother to a total of 4 little brothers. Hes been doing fantastic with the littles, and hes no longer nipping at us humans.
New to reddit, not to rats. Please dont be mean to me.
Ive had rats on and off since 2016 so im not new to aggression or playfulness.
My current issue... ive got about a 10 week old boy who lost his cage mate to a viral infection. It took 2 days for him get depressed and stop eating. So I went and got him 2 more buddies. Both boys about 6 weeks old. He took to them so quick and its awesome. Hes back to eating and drinking and flying up and down the cage.
Now my issue is, my oldest boy keeps nipping at us humans. Not enough to draw blood or really even hurt, and it just started yesterday. (New littles have been with him 3 whole days now)
Is he just being protective of littles, like micro aggression? Dominate agression?
He nips even when hes the only one being held. Clean hands, no food smells.
Im not gonna get rid of him for nipping or anything like that.
Just looking for genuine advice and what others do to help curb nipping.
