I would think there would be more objects trailing a (small) asteroid, yes.
But what forces releases a smaller fragment from an asteroid/meteoroide?
Rotation, tension in the rock, gas release underneath? Some of these forces
could
be strong and send them forwards with some speed.
I'm not shure what quantitive effect of solar wind etc.would have in the
long run, but yes
I would think asteroids in some ways resemble the situation you have with
comets, but the material
in the latter is of course much lighter, and a greater effect of the solar
wind is felt.
It's a bit beyond me, and it's very hard to observe debris clouds around
such small objects.
