Yep, those are the packages for both dewormers that get tapeworms. Both are paste. The Z-Gold is orange colored, and not a very thick paste. I'm not sure about the other (consistency wise) as I've used it only on my horses...never a need to dose it onto my fingertip.
I usually actually try to buy it over Z-gold (for my horses) because it's got a higher % of active ingredients than Z-Gold. (it's a few bucks more usually, too) For chickens, I'm sure Z-Gold is plenty effective.
Dawg is right, you should be able to find one (or both) at a
TSC, Atwoods, feed store/co-op...tack store, etc. It'll cost about $10-15, and should last for several dewormings unless you use it on a very large flock. Just stick the cap back on it, shove the syringe back in the box and keep it somewhere it won't freeze.
