4.5 month old kid, diarrhea and weak

One of my triplets has diarrhea and is clearly dehydrated. Will walk a little but weak wobbly and is standing and looks a little hunched like her abdomen bothers her. I gave some spectoguard Scour check oral and she nibbled some fresh leaves I picked. She nibbled a little goat feed, but I was afraid to give much. She has no interest in water, but was really nibbling and trying to suck on my hands -- she is not a bottle baby and is older-- but I had some goats milk in the fridge so I warmed it up and gave her about 3 ounces (all she wanted) and she took it pretty well. More chewed and swallowed than sucked, but I figured at least it was some liquid. Is this okay to offer her milk again if she wants it? Any other tips?

Background: Mom has been semi--weaning them but I recently had construction start at the house and had to turn off the electric fence. Breakers tripping and gate latches left open and other...
SO I had everyone up in a smaller pen and have been feeding hay and small amount of goat feed. It was a food change as they have been almost entirely pasture with just some supplemental goat feed a little in the mornings. They always have free choose loose minerals.

 

no good way to get a fecal but I have corrid. should I start that?

 

just to help me learn - what symptoms do you usually see with overload of coccidia?

 

update: She is now on corrid and she just finished a 3 day course of spectoguard. She has an appetite and her color has improved but still is on the pale side and stool is firmed up. Coccidia even I could ID and yes the local small animal vets "could" see but they won't treat goats and and won't even take the sample. I have asked before. There is a large animal vet about an hr and a half away I can (and will) run a fecal to, but not until Tuesday because they are closed tomorrow. And with it being a 3 hour round trip it's tough for me to get there when they are open around my work schedule.
She is better but not great. She has not bounced back like I hoped so I do think she has something else too maybe. She is eating and drinking but is still weak. She will walk and browse but is slow and she tires easily.
lastly I have tech experience myself with small animal - I would really really like to find my own microscope. Anyone have recommendations on good affordable ones?

 

SO Tuesday we made it to the vet and she has heavy load Barber Pole worm. Very anemic and we still are not sure she will make it, but started a deworm for her with panacure to be followed by cydectin (and all the other goats just in case) and he gave iron injection. She is still hanging in there and eating and taking electrolytes in a bottle (weird that she will take a bottle but anyway to keep her drinking is ok by me.) MY stupid TSC does not have any red cell (except the poultry one? they said) and I need to find some today, so I'm calling around... So ya'll cross your fingers for her that she can be a tough girl and pull through.

 

today she is having a very bad day. I am going to give another iron and B12 injection and get her a higher protein feed. How much pellet feed can I offer. She seems to nibble at it but I don't want to over balance her if she is not eating much else. yesterday she was grazing my front yard but today her appetite is very poor.
She only weighs about 20lbs
