Bat on my sidewalk?

I walked out for a smoke about 45 minutes ago and saw a bat just laying on the side walk. It seemed to have fallin from the tree or lost its grip on the roof. I looked at it closer and saw it had two baby bats attached to its underside. I grabed a paper plate and a broom and swept it up onto the plate and put it on the backyard table so the cats out front wouldnt mess with it. i went out there about 5 minutes ago and it was no where to be seen. I was just wondering if the bat with the young attached to its underside took flight or something.
