Tired bunnies?

Does anyone with different breeds of rabbits, find that smaller breeds (and maybe larger) tire out quicker?

I let Matilda(mini-lop) and Grayson (mini-lop cross) free range for the same amount of time, but Matilda can never keep up with Grayson! shes fast asleep and he still seems to be awake and hoping about?

Also notices this with my bigg rabbits! they sleep more than my lops do?

Is this just personal to each rabbit, or do smaller and larger breeds tire faster

my yuri is a mirror image of your matilda and she NEVER runs out of energy... where as yuki snoozes in the tunnel

my mini lops always seem tired they will have a quick run around then back for a lie down lol
