Treating mixed flock for roundworm

[HollyOakFarm]

Hi all,
I have a mixed flock of 40ish chickens - in 4 different houses, same yard..... 7 geese, 3 turkeys and 4 ducks.
I just had a routine fecal done on my chickens and it came back with roundworms (1st time for me). Vet said to worm chickens with Albendazole. 2 week egg withdrawal.

Question:
Should I worm the turkeys, geese, ducks at the same time with the same medication? (I don't have fecals back on them yet).
Is it correct that average size chickens get .50ml per bird? I'm assuming my Olandsk Dwarf (bantam size birds) would get something more like .375ml? I'm terrible at math, so I want to be sure. I'll attach a pic of what I ordered. Will I need to do a follow up dose? Vet said one dose, but I've seen people saying 2 are needed.
My plan is to do everyone at night after they roost. Who has done this? Did you figure out any tricks to make it go easier? What type of syringe did you use?
Any tips are welcome.
Thank you!

Personally I would wait for fecals before treating the whole flock.

Round worms (as with most parasites) are species specific, so a case of roundworms in the chickens doesn't translate to roundworm infestation in ducks and geese.

The exact dosage for Valbazen or albendazole is 0.08ml per pound of weight given orally once and again after 10-14 days. You can get weights with a kitchen scale or by holding a chicken on home scales, and subtracting your weight.
