Is she blown up? If yes, then she may well have a blockage further inside her intestines, but if she is happy and bouncing about she may well be "quite clean" and/or have a very attentive mama... is s/he drinking from the dam?
I had a goatkid this year that had to be pts, because of this, she passed meconium ok, was keen to drink from the bottle but distended stomach by 24hours and very unhappy girl...
