That is a good question, eggs should be all gone by the end of five days- especially since the standard dosing of fenbendazole is three days. I might suspect resistance and I would rotate onto something else like pyrantel or prazi/moxi. I will ask my boss though.@rbaker0345 , after a thorough worming for whatever worm egg is found, how many days before one can expect to see no eggs? For example, float finds capillary eggs, bird is treated for five days with proper amount of Safeguard, then another fecal is done on day six or seven and still eggs... not as many, but they are still there.
