Recently Used valbazen for possible Gape, can I use again for Other worms after only 3 weeks?

[Jenbirdee]

1 yr old runner duck with coughing & raspy quack
One of the things I tried was Valbazen at the gapeworm dosage in case IF it was gapeworm
Also tried Tylan antibiotic in case IF it was an infection
(Have since decided its aspergillosis and am treating with OxineAH for that)
I am treating the rest of the flock this week with Valbazen (at the regular dosage of 0.08ml per pound once and again in ten days)
Should I include this runner duck?It has only been 3 weeks since she had it

You can hold off on the runner duck until next time you dose your flock.
