Quote: No you don't use ivermectin pour on for worms. That works for mites and external parasites. They might absorb some of it but not enough to do an effective job. You would need Ivermectin injectable.
I mentioned ivermectin because she said she had some. I actually use Safeguard wormer one time and ivermectin the next. Safeguard will kill capilliary worms, cecal worms and tape worms where invermectin won't kill cecals or capilliary worms. Neither is actually rated for tape worms but according to HEChicken the ivermectin works better than Valbazen on tape worms. I tend to believe that, because they are the hardest worm to alleviate. Panacur is what vets usually use in a three day dose for tape worms and that is the same medication febendazole, that is in safeguard.I use Valbazen for worming because it works over time and will not overwhelm the bird's system with too many dead parasites. Just learned that this year. Previously, I was using Wazine, first, and then Valbazen. I switched to Valbazen because it is the only wormer effective against all parasites, the others kill most, but not all of them. I found that out when I added some birds from another flock and passed one of the birds to a friend. She found out it had the one kind of parasite not covered. So embarrassing, but it was a good thing she actually saw the parasite in the droppings and could determine what kind it was. I never saw them in the droppings but the one bird just had a continually messy backside until my buddy figured out what was going on. Problem solved with Valbazen. I think Ivermectin works so well for Danz because she never gets that particular parasite, and probably most people don't. I've had it here so that's what I will continue to use, just in case it's still in the soil. Valbazen is a lot of extra work also, you have to syringe it into their mouths. It is also expensive.
Ivermectin has a reputation because it is the medication used to prevent heart worms. If it kills a bunch of heart worms in a dog it can block the valves and kill the dog. So it has a reputation of being strong. It is actually very safe as a chicken wormer. Any wormer is going to be hard on any animal. The important thing is to make sure the animal is in other wise good health and supplement with probiotics or good greens etc while worming. They actually get very little wormer at a time cause it is mixed weak and they hesitate to drink any more than they have to.
All wormers have their benefits I guess. I figure by worming one time with one and the next with the other I am catching all ends.
Ah ha! That makes great sense and seems like the way to go. Valbazen is so expensive and if I can cut costs, I am more than happy too. Thanks, Danz! You always know your stuff.
