I won't treat for worms without getting a fecal float at the vet. Any vet doesn't have to be avian to run a float. Cost is $18-25 at my vet (too high really). And I do a flock sample, herd sample, or pack sample. In other words combine several collected sample from an individual species into one.. Like the goats, dogs, or chickens. It saves $, still gives an overall look, and is an accepted practice. I also bough a microscope to run my own samples since I have so many animals, the vet gets pricey and isn't always an option. But I'm still gaining that skill.
The reason I get a float is because not all wormers treat all species of worm. And I don't wish to treat for what I don't have while accidentally not treating what I do. Wormer meds are actually poison and hard on the system of the birds. So never worm an ill bird without verification. Under heavy load round worm and tape worms *may* be seen in the droppings. But all other species stay inside the intestine and only their microscopic eggs will pass. I would treat if I saw round or tape worms in droppings as that's pretty clear you do have them.
So in 8 years of raising chickens... I have never wormed yet. Partly because I didn't know you "needed" to. Once I learned, it was still hard to spend the $ on a float instead of just treating... I have one gal with muddy bumm all the time, and one of my dogs was scooting their butt on the ground recently.

Both symptoms that people will SWEAR is worms.
So I spent the funds for 2 floats in this instance... and both came back NEGATIVE for worms. So now I didn't have to spend the time, energy, or $ treating AND withholding eggs! And my birds and dogs were not subjected to poison needlessly. The worms also aren't building their resistance to the drugs I'm not using.
And while I do work hard to maintain my coop and pasture... worms are part of the environment. So not getting them doesn't mean I'm doing anything better... just that maybe it isn't as much of an issue at my location. And my floats prove that no matter what other people say or think doesn't mean their right. Every situation will be unique. I'm not saying they're wrong either. So just use the information you have available at the time and make the decision you think is best or makes the most sense. If you learn something new, switch it up.
I used to live in the "high desert" here in California. Elevation was only 4000 feet, but we still got some snow and around 100 f+ (38 c+) in the summer. It had a beauty all it's own! BC is actually one of the very few places I'm interested in visiting. It just seems so beautiful and comparable to where I currently live.
Then I had to wonder if you are Christian, from your user name... but I'm thinking maybe a Pulp Fiction or a Samuel L Jackson fan?
Hope you have a great day!
