Thanks for asking. She is doing a bit better - more energy and clearly eating something (mainly forage not commercial feed) and drinking.
But the big news is that I did what the vet calls 'a flock fecal' (everyone contributes!) and that picked up worms and coccidia (honestly I am not convinced the coccidia load is more than would be normal but the round worms are). So I am just waiting on the worm medicine to be delivered and they are all going to get dosed. I am obviously hoping this is in fact what is wrong with Minnie and that it cures the diarrhea that both Maggie and Dotty have had for a while now. Prior fecal tests were negative but the vet consulted one of her expert contacts who said that sometimes a flock fecal is a better way of detecting worms.
So, fingers crossed for a miraculous recovery once I get to treat her - I am looking up doses on Corrid right now (I have that in hand so can start that treatment as soon as I figure out the dose).
