How do you worm yours then: paste, liquid pellet, what?
There are many different types of wormers on the market; therefore there are different administration methods depending upon the wormer and your needs/preferences. A number of the wormers come in several different forms, so you have a choice of how to administer.
Wazine (piperazine) comes in a liquid form that is generally added to the water.
Safeguard/Panacur (fenbendazole) typically comes in a paste tube and you administer pea size blobs to them either by inserting it into their beak or like one earlier poster suggested filling raspberries (or any other food) and that they will eat. Depending on the livestock targeted, it also comes in pellet and liquid.
Pyrantel comes in an suspended liquid and is applied by droplet into each bird's mouth.
Ivermectin is just like the dog/cat stuff and you administer a dosage of liquid at the base of the neck between the wings.
Hygromycin B currently only comes in pelleted form that you administer by mixing it with the feed.
Each wormer targets a specific type of worm, some target a more broad range of worms. Depending upon your preference and needs, generally it is best to rotate wormers as worms can build up a resistance to a particular type.
Of all the wormers mentioned, only Hygromycin B is FDA approved for chickens used for eggs for human consumption. (Which matters if you sell eggs...doesn't if you don't and don't care). It is the only one that does not require egg withdrawal (tossing)...you could chose to still toss if you desired. Slaughter withdrawal is 3 days.
The rest do not carry egg withdrawal instructions on the labels as they are not sold for egg layers. Many use the slaughter time for withdrawal for poultry (if given). The general rule of thumb is 14 days for egg withdrawal from the last dose. You generally need to dose once, then dose again in a week to 10 days, depending upon the medication and type (READ label!)...so it usually means tossing eggs for about a month.

EDITED TO ADD: The -zole types (and Hygromycin) work by starving the worms from nutrients by interfering with the metabolism of either protein or an essential food element; -mectin works by interfering with the neural system within the worm causing paralysis and death. The -zoles are generally poorly absorbed by the gut, the -mectins are well absorbed and hince systemic (which is why they are used for the parasites for River Disease which often target the eyes).
