Hello fellow worm bin people!

So I started my bin about a month and a half ago and things seem to be going fine, smells good -looks nasty! One thing I have noticed though, there seems to be small white spheres all over in there. They are about the size of ballpoint pen balls( very small). I thought they were eggs of some type, but have not noticed any bugs hatching out, and I think I would cause there are hundreds of these things in there. Does anybody know what these things might be? Thanx!
