I would like deworm my flock of twenty chickens, but I don't want to have to do each chicken individually. I read that I could use Safeguard in their water, but I need to know the withdrawal time, if there is one.
 
Do you know if your flock has worms? Knowing if and what kind is important before you work them. Not all wormers treat all types of worms.

Usually my vet will send a fecal sample for me even though they don’t treat chickens, and it’s not an expensive test to have done.
 
Yes... you can dose by drinking water. Fenbendazole has a very high ld50 and no withholding.

You can dose them directly with panacur oral solution at 10mg per kg of bodyweight. Or 1 millilitre per litre of water. Which is 4 millilitres per gallon for imperial folks.
Double check the dosages. As there is more than one concentration of panacur drench perhaps.
There is plenty of literature out there, and on this forum of people doing it this way. It's commonly used by many aviarists.



here is a 25 page thread on the subject where safeguard is also mentioned. Maybe that will help decide a dosage for safeguard. I use panacur drench. I believe they are the same thing. But I don't know of concentration differences:

Wow, thank you! That is helpful!
 
I am the opposite. I wanted to individually dose each of my 30 odd chickens, cause I wanted to be sure they were getting the correct amount in the shortest time possible and I didn't want to have to confine them for a whole day, they love their free time.
I found a really effect method, for me, was to (one at a time) measure out their dose and soak some bits of bread in it then leave them in a dog crate with the bread while I measured and prepared the dose for the next one. A couple didn't like the taste but I just had to place the bread in their beak and they would swallow it.
Mine are actually due for the second treatment today... it'll still take me a couple hours but it'll be the last one for awhile.
