@coach723 how do you give them the dose with the syringe?

If one bird has worms, most likely the others have them as well.
Get either safeguard liquid goat wormer or valbazen liquid cattle/sheep wormer. Also get a syringe without a needle, a 3cc syringe is good enough.
Go out to the coop early the next morning without letting them out of the coop and bring your syringe and bottle of wormer with you. Shake the bottle well, then pour the wormer into the bottle cap and draw up 1cc of the safeguard OR 1/2cc valbazen (whichever one you're going to use.)
Worm your birds prior to letting them feed. Your birds will be hungry after being cooped up all night and so are the worms, except you're going to feed the worms a special treat that'll get rid of them. The wormer will be more effective eliminating the worms when they havnt absorbed nutrients. You may or may not see worms excreted in feces after worming. Most of the time they are absorbed as protein in the chickens digestive tract.
Then open up your coop and snatch a bird off the roost and cradle the bird in one arm and grab your preloaded syringe with your other hand. Use your hand that you are cradling the bird with, and pull the wattles down with your fingers/thumb and her mouth will open. She might struggle and shake her head but dont let go, she'll tire and settle down.
Then, if you're using safeguard, only shoot 1/2cc into the birds mouth at a time. If you shoot the full 1cc into the mouth, some of the liquid might flood into the trachea and then there would be big trouble. Only shoot 1/2cc at a time and immediately let go of the wattles so the bird can swallow the liquid on her own down into the esophagus. (I cant emphasize that enough!)
For the valbazen at 1/2cc dose, the same applies as far as releasing the wattles so the bird can swallow the liquid on her own.
It might be best for you to practice this on one of your birds but without a liquid in the syringe.
It would be ideal if someone were to hold the bird for you while you pull the wattles down and shoot the liquid in the birds mouth. Again, it's imperative to let go of the wattles so the bird can swallow the liquid on her own.
If you use safeguard, repeat this procedure every morning for 3 days straight.
If you use valbazen repeat dosing in 10 days.
The reason why you redose is to kill worms hatched after the initial dosing.
Just for your info; both safeguard and valbazen are excellent wormers. They not only get rid of large roundworms, but other types of roundworms in chickens as well.
