Reading this thread with great interest...dealing with a 10 year old female King Kong Blood Parrot who has stopped eating x 3weeks, not bloated or emaciated, but has all the symptoms of Hex. Had my vet look at a fecal sample and water sample and she said she " sees a Jungle " and doesn't know what is good or bad. Treated for hex with metro once already to no avail. Vet saw " eggs " of some sort. Going to try epsom salt , but she isn't eating, so do a water tx with epsom salt ? IF it's worms, where do I buy Levasimole ?
