As I posted on your other thread, you really need to get this little goat to the vet. If you can't afford a vet visit, maybe the vet would give you a phone consultation and recommend what to give the little goat. Or, try and work out a payment plan with the vet. You can't just sit back and let it die. Possilby call the man you bought her from - he may know what to do. If you haven't seen her drink water once in over a week and she had diarreah for many days, and has been completely lethargic, she won't last much longer.
What are you worming her with and what shots are you giving her?
Please call around, to various vets offices, until you find one that can give you a recommendation.
By the way, it's best to keep related "Emergency" thread together so that someone will have all the information needed to help you.
Here's the info from the other post:
"My baby goats has bad diarrea she is eating but she is not like my other baby goats she does not jump around and play and yell she just sits around in the hay box could this be from eating to much grain? its getting all over the back of her it's filthy plz help"
"I took all of her food away just clean water, and have been giving her petobismol. Tell me about this so my other two pygmy goats i got at about 1-2 months old and they always ran around playing and jumping and yelling but this goat is FAR diff she hardly ever yells she never runs she just lays around in the hay box or is always laying around she has been here about 5 days"
