Worms after recent treatment!?

[sweetpumpkinfarm]

We have 4 hens that are in a 16ft run w/sand and a spacious roost with hemp bedding on the floor. They free range in our fenced in suburban backyard in the day. We do Ivermectrin de-worming (as a preventative, they've never had them that I know of) and just did a round in July but this am when I went to clean out roost I found a big pile of worms. They are all doing fine and not showing symptoms---planning on another round of Ivermectrin plus all the natural preventatives/treatments. But how is this happening, or is it just something that can happen environmentally? I scoop poop multiple times a day from sand (& they are also in large yard a lot so not inside al lday), we have a poop board covered with newspaper that's cleaned outdaily, I use DE everywhere and maintain a super clean coop. Our egg prod is normal and girls seem to have normal personalities....

Those are round worms.
Ivermectin lost its effectiveness on poultry parasites years ago, especially with routine exposure.
You need to get some Valbazen, typically under the brand SafeGuard.

Safeguard 10% Liquid Goat Dewormer or 10% Equine Paste dose is 0.23ml per pound of weight given orally once a day for 5 days in a row.

There are no natural remedies or prevention, unfortunately, I'd also stop the DE since it's bad for you and especially your birds to breathe long term

SafeGuard and Valbazen are different wormers. Valbazen or albendazole dosage is 0.08 ml per pound of weight given orally once and then repeated in 10-14 days. That comes out to about 0.5 ml for a 4-6 pound chicken. SafeGuard Liquid Goat Wormer or the Equine paste are both 10% fenbendazole. Dosage of those is 0.23 ml per pound of weight given orally for 5 consecutive days. That is about 1.25 ml for a 5 pound hen. Either one treats round, cecal, capillary, and gapeworms. Be sure to shake either bottle well before drawing up a dose with a syringe since both settle out.

Sorry, I've been up since 4, nothing clear as I'd like.

I would worm your chickens with Valbazen (albendazole) or SafeGuard. Ivermectin has been overused to treat mites and has lost some of it’s effectiveness for worms in recent years. Generic albendazole is easier to find than Valbazen online these days, and SafeGuard Liquid Goat Wormer is found in many feed stores. Syringes may be purchased there as well.

Using the dewormers frequently as a preventative without testing to see if the chickens have a high worm load in the first place is one reason dewormers eventually become ineffective. It would be best if you can find a vet or lab that will do fecal testing for you to keep an eye on the worm (and bacteria and coccidia) load. That way you won't overuse dewormers or use the wrong meds.

What is your climate? Maybe consider a different run litter. Sand does not compost and can never really be completely cleaned.

How often you worm birds depends on your environment. Warm moist or wet soil may require frequent worming. Cool/cold soil or hot desert like soil/sand may require less worming.
Most benzimidazoles are good for 28-30 days after initial worming.

Our soil here where we live is warm and moist most of the year and I worm my birds monthly with Valbazen. I have used Safeguard in the past as well as other wormers.
I have sand in all the pens, coops and most nest boxes. Sand helps keep everything dry, deters insects, dries quickly after it rains and is easy to scoop poop. Think beach.

Don't chickens originate from warm and moist places? It just doesn't seem right to me to have to use these man-made drugs so frequently. There's got to be a way to prevent worm overload by improving management practices and breeding healthier birds. But how to do that, I don't know...Sorry, just ranting.
