I would think that good management practices would include diagnostics, especially when people *are* suggesting that birds only get an overload of worms when they have an underlying problem.
As for hundreds of dollars, wormers and fecals are cheap, and many states offer low cost or free necropsies. Sure, some states do charge a lot, but even those that do charge will sometimes waive the fee if one explains their financial situation.
That's what the look see at a little clump.of soil here and there can do.. I borrow the $15 microscope kit of the kids and look at the soil..since that's where most worms and eggs actually come from, poorly managed poo impacted soil![]()
What are you looking for when you look at the soil?
