Poo or Paste butt?

[kneit099]

So the 6 of my chicks that have survived have a little brown, crusty stuff on their bottoms...

Is it normal for some to have this or will they always have a little bit of stuff on their bottoms?

Thanks in advance.

Found one of mine with pasty butt, cleaned it off with warm water on a paper towel.
Read somewhere about applying olive oil around the vent ... is this helpful ?
