actually the charcoal was the best thing for her. activated charcoal is estimated to reduce up to 60% of poisonous substances by adsorbing the toxins/chemicals, reduces their toxicity and works throughout the entire length of the goats digestive system.
Activated charcoal itself is odorless, tasteless, and
nontoxic and will not be the cause of upsetting her stomach. charcoal is considered to be the most effective single agent available for absorbing almost any ingested toxin/poison/chemical.
If she is shivering, have you taken her temp? If it is low, get her warmed up with a sweater, heating pad, towels warmed in the dryer or a heat lamp. Even if she 'looks' horrible (and who wouldn't after an ordeal like getting their stomach pumped?), she is drinking and that is a good sign. If she if 'following you around' then she is at least active to some degree...also a good sign.
But I
would give her some probiotics, kefir (which is superior to yogurt) or yogurt containing 'live or active' cultures to help restore healthy rumen activity.. You say the vet found 'azalea and boxwood' in her gut, it really is a good thing she didn't eat any yew, because she probably wouldn't have lived.
Everyone should have activated charcoal on hand in case of accidental poisoning. You may be able to get some from your vet, feed store or tractor supply. I bought two tubes from Jeffers to have ready in case of emergencies.

Having her stomach pumped/charcoal may be what will save her. Give her Probiotics and electrolytes, and let her tummy recover. Keep offering the bottle, she'll eat when she is ready. Is she eating hay yet at 11 weeks, and does she have it available in the barn if she gets hungry?
Installing a sturdy goat-proof fence and gate should be a priority. Goats are known to be able to get out/over/under/through fences etc. if they want to badly enough. If they get out again you may not be as lucky. We don't have ornamentals (I simply won't have them with goats) but across the road there are yews in the neighbors yard and I worry if my goats ever did break out they'd eat the yews. Yews are probably one of the most toxic plants and are poisonous to all animals.
Ps. glad to hear she seems to be improving.
