I've used Valbazen (Albendazole) liquid - Kills pretty much all the internal parasites of concern in chickens, including tapeworms. Kills worms over several days, reducing the risk of worm impactions.
Small birds should get 1/2 cc, large birds 1 cc; repeat in 10 days.
Discard eggs for 10 days after treatment.
Or what Dawg53 recommends - quoted here from anther thread
"I recommend the equimax (Ivermectin and Praziquantel equine dewormer), it's easier to administer and only twice. Valbazen is effective but requires multiple dosings at higher doses and withholding feed (for tapeworms.)
I recommend withholding feed for 24 hours prior to worming when dealing with tapeworms anyway; no matter if it's equimax, z-gold or valbazen. Withholding feed for 24 hours makes the wormer more effective as the worms will be starving. Feed the hungry rascals equimax lol.
After worming, wait 4 to 5 hours before feeding your chickens. The chickens will be starving also. Only feed them a little at a time. If you dont, they will gorge on their feed possibly causing impacted crop or gizzard. Gradually increase their feed as the day goes by back to normal feeding.
Always worm your birds first thing in the mornings. I like to snatch them off the roost one at a time just before or right at sunrise and worm each one individually, then release them into the pen. I dont let them free range until later in the afternoon (remember the gorging issue.)"

Dose is 0.03 cc per pound or 0.16 cc per 5# of weight. 14 day withholding for eggs.
I have not personally withhold feed for 24 hours, but it sounds like a good idea if you are treating tapeworms. Sounds like both work better for tapes if you withhold food, then repeat dosing.
