Yikes, $150 for a fecal test?! My avain vet does them for $50.00 and that's still to much to be doing them on a regular basis so I just deworm twice a year. I rotate between Valbazen and Safeguard. I occasionally have the state lab necropsy a bird when I loose one for whatever reason, just so I know what's going on, and parasites have never been a problem.
