HELP!!!

[Lisa Horner]

One of my baby gerbils (almost 6 weeks old) has a problem.  Her bottom is
furless!!  And, when she poops, the poop looks like a greenish wet worm.
She pooped right in the food dish while she was eating.  Please help!!  What
can I do to help her get better?   I separated her from the others (3
littermates, mom, dad, and the mom just had another litter of 3 this
morning).

Thanks a lot!!!

Anxiously waiting,

Anthony
