future problems?

[buzz]

Hello, I have three gorgeous boys but theres alot of fighting behaviour with the oldest about 3 months and the youngest about 8 weeks or so I was told. I was wondering if it is dominance behaviour to lash out with hind feet as well as mounting. At the moment I can't see a serious problem as the fights don't last long and they sleep together but the youngest is definatly fiesty and I was wondering if its common for degus to fall out over time.

Thanks
Kate
