Chickens with worms (Advise on what to treat with)!

[casportpony]

I used Valbazen when my chickens had worms and it worked very well.

Valbazen does work very well.
Safeguard is good too, but you have to use more of it.

By the time you see a worm, they have a pretty bad infestation. I'd personally treat with whatever is easiest to find so you can begin treatment right away, and you'll want to treat the whole flock since they'll all have passed it around by now.

I don't have Valbazen experience but can share my experience with Safeguard. Roundworms unfortunately love our soil.

I've had good luck with the 10% liquid at the dosage per @Overo Mare. It's easy to find at Tractor Supply in the goat/sheep section.

Write up a checklist of dosages for each bird. Grab a needle-free syringe. Prepare an individual serving of a favorite treat [rolled oats, in our case]. Then separate a bird so she can have the treat all to herself, squirt her dose on top, and let her enjoy the treat.

Check her name off the list, repeat. Do the whole circus again 10-14 days later.

Most say to not eat their eggs 1-2 weeks after the last treatment. That's a bummer. But roundworms that severe are well on their way to starving your chickens, sooo, small price to pay. Good luck!

IF there IS an infestation of large roundworms, use Valbazen. Valbazen slowly kills worms over a period of several days. No need to worry about toxic worm overload as with other wormers.
Also, worms can cause sloughing of intestinal lining, particularly capillary worms and large roundworms. Valbazen will take care of them. So will Safeguard. Liquid wormers are preferred since they get into the bloodstream quicker.
