Should I worry about this bunny?

[UnlabeledMama]

I have 4 baby bunnies that are about 7 weeks old now. All from the same litter and very sweet. We got their sire as well.

One of them (my daughter's favorite, of course) is small then the others and seems fragile when you pick it up. The other three are solid. I can feel this one's bones through the fur. It eats well, and the others cuddle with it - it doesn't seemed to be bullied by the others. It's eyes are bright and it's active. It loves people and everytime we go near the cage it runs to the door and wants attention. It's siblings are a little more stand-offish. Should I worry? Or is it just the runt?

Some bunnies get a slow start, and may be smaller than their siblings for that reason. Though they may be a little behind in development, they usually plump up when they get onto solid food. A bunny that seems fragile is a different situation. I know, we all tend to root for the underdog, but most of the time when an animal isn't thriving, there is a solid reason for it. IME, bunnies that just seem "off" aren't destined for long lives.

That's what I was afraid of.
