worming what to use

[happy place]

hi guys
thought id throw this out for disscussion cause for my chooks i use a wormer (cant remember name ) which has no egg withdrawall you add it to their drinking water at one measured squirt per 50ml of water per a bird but how do i ensure they all get a share as i have already had one girl who i thought i was going to loose but turned out to be excesive worm burden discovered in time to worm her and speedy recovery followed
i started their monthly worming today but cant be sure they all drank the wormer is there a drenching system where each bird can be dosed indevidually so i know they have all had some
any ideas comments or recommendations welcome thanks
