Betty the two year old Brahma came down with jello-green diarrhea two weeks ago. She almost died, but I pulled her back from the brink with some amoxicillin. The diarrhea changed color from green to dark blackish brown, but it's still watery. She only has regained some appetite in the last couple days, and her ornery disposition has returned. She's been isolated all this time, but I let her visit her mates from an adjacent enclosure and it was touching to see them all greet her with a touching of beaks and murmurs. She has occasional solid poops, but they've been rare. Should I keep on with the amoxicillin or can someone suggest something better? No sign of worms or mites and Betty looks great otherwise. Help, please!
