Help! Dewormed chickens STILL have worms!!

I feel completely beaten! I dewormed my hens with zimectrin-gold horse dewormer, then re-dosed ten days later. For two or three weeks I haven't noticed any worms in the droppings, but now they are back!!! What is a person to do to get rid of these things?????

If anyone can help me out here, I'd appreciate it. I'm at my wits end, and after trying three different dewormers that haven't worked, I'm at my wits end. How do you beat these things?
You could try just praziquantil, it's sold in the dog and cat sections of pet and feed stores. If you decide to do this, let me know and I'll look up the dose for you.

Kathy, have you tried this on your own chickens? I'm pretty sure I have the worms narrowed down to tapeworms. But I thought the zimectrin gold treated tapeworms and I'm still having the same problems even after two doses of z-gold. I hate to keep spending my money on products that aren't working out.
Thanks for your thoughts on this - I appreciate it!
 
There's no doubt that tapeworms are tough to get rid of, your chickens probably have access to infected insects, not much you can do about it. Here's a link regarding cestodes (tapeworms.)

It's possible they are resistant to praziquantel. You can purchase Valbazen (links provided below.)

Withhold feed for 36 hours. Then give your birds 1cc valbazen orally undiluted. Wait 3 days, withhold feed 36 hours the 4th day, redose the 5th day 1cc orally undiluted. Wait 3 days, withhold feed for 36 hours the 4th day, redose the 5th day 1cc orally undiluted.
Three sets of seperate dosings.
If you have birds that weigh over 8 pounds, increase valbazen dosage to 1.5cc's.
After each dosing, dont give them feed afterwards for at least 3 hours. Then give them a small amount of feed to eat...if you dont, they will gorge on feed due to hunger, then it's possibe for them to get impacted crop due to gorging feed. Once the three sets of worming are complete, gradually increase their availability of feed over a few days back to normal.
I've done this with success in eliminating tapeworms and continued worming every two and a half to three months with valbazen rotated with safeguard prior to ever using zimectrin gold.

I'm thinking I should try getting a vet to identify the worms first before I but anything. Maybe I'm just treating these things with the wrong ingredient! Too bad that Valbazen doesn't come in smaller quantities. It says it treats 450 birds - I only have 5 chickens!
 
Valbazen is a liquid. To administer it, use a syringe without a needle to dose orally. You can pull the hens wattles down firmly, and her mouth will open. Then squirt 1/2cc into her mouth then immediately release the wattles so that she can swallow the liquid on her own. If you dont, she could aspirate. Then pull her wattles down again, and squirt the other 1/2cc into her mouth. You dont want to squirt the full 1cc into her mouth, she wont be able to swallow it all at once and may choke or may aspirate....1/2cc at a time orally.
 
Do you know if it's possible to buy Valbazen in smaller quantities? Like I said, I only have 5 hens, and with all the different things I've tried, those five hens are getting very expensive. I don't need a bottle large enough to dose 450 birds!
Also, I administered the Zimectrin Gold once, and then again ten days later. Their last dose was about three weeks ago. Is it possible that I am just seeing the last of the worms being expelled? I don't think all of the hens have the wormy droppings - possibly just one of them. I'm considering just waiting to see if the worms continue, and I'd like to start adding apple cider vinegar to the water, just as a backup/preventative measure.
My hens all look and are acting healthy. All are either going through or finishing a molt, and they are looking great, not losing weight due to worms or anything like that. What does that say about this whole worm problem?
Thanks again to all for your thoughts. I'm learning as I go, but your suggestions are appreciated!
 
Well... I have come to grips with the fact that my chickens have tapeworms and none of the prior dewormers have remedied the problem.

After using Wazine17 and discovering it only kills certain adult worms, I used SafeGuard, which I discovered doesn't kill tapeworms. Then I dosed twice with ZimectrinGold horse dewormer and my chickens still have worms. It looks like I need to loosen up my wallet and put the money down on Valbazen liquid dewormer. After researching a lot of stories and accounts on BYC it has received the most positive feedback as a broad spectrum dewormer that will target tapeworms. My question now is, how long does this Valbazen keep? Considering that I have five chickens and a bottle could last at least several years, does it have a fairly long shelf life? I can't keep spending money on dewormers that either don't work or won't keep. It will be worth it if it lasts a long time and I can use it for future deworming.

Thanks all for your help! This has been one long and arduous (and expensive!) learning process. Who knew?
