That baby really may need to go to the vet. She may have picked something up like Coccidia. My little Hootie girl had diarreha when she was a tiny baby and I thought it was just from food or something she ate. But I finally took her to the vet and she definately had coccidia. But after I started her on meds, the coccidia cleared up right away. It is better to be safe than sorry with these little bitty ones. Please take her to a vet to have her checked for parasites. Hope she feels better soon.
