ASAP! Best de-wormer brand in Canada?

[WellingtonCoop]

Hi all!

I need a de-wormer ASAP. Our flock definitely has parasites of some kind as two have died in the past week after making wheezing noises and shaking their heads and necks. Gapeworm??
Any Canadians here that can recommend a brand to try for treating our entire flock? We’re in Ontario.

Thanks so much !
