This is when must must look at the whole picture... Flock history, previous medications and wormers used, weight of bird, etc.One thing that worries me is all of the reports of tests given by vets coming back negative for so many things....... I realize that when a vet does fecal exams or floats, they are devoid of parasites. I guess my point is, if you get test results from your vet that are negative, if you do not see improvements with treatment in a day or two, maybe it is time to run more fecal exams.
Did that rambling sentence make sense?

Edited to add: That came out wrong... of course one should always look at the whole picture, not just when one gets negative fecals.
