What worms do you want to treat?

 

[Shadrach]

There are better options for treating internal parasites than Ivermectin. It seems that in some areas Ivermectin is no longer effective. The worms have built up a resistance to it.
If you are in the USA there are many other options that are effective and should you find a flubendazole treatment there is no egg withdrawral time.

Ivermectin can be administered in just about every way possible.
The instructions are on the box as to how the product is to be administered; for example the photo in your post #2 states on the box that it is to be given by injection.
Topical in this instance for Ivermectin is called "Pour On," as stated on the box to be administered on bare skin on the back of the chickens neck. It is quickly absorbed into the bloodstream.
You would be better off using Safeguard or Valbazen to worm your birds.

Flubendazole is not approved for use in laying hens in the USA.

However, fenbendazole (Safeguard, Panacur, Aquasol, etc) is approved for the treatment of roundworms & cecal worms when given at 1 mg/kg for five consecutive days.
