Hi! I’m also new to the forum and living in BC. I suspect that Beau Peep Farms may be able to help you out with your query. Give em a call and see! Cheers!
If you haven't yet, please make your birds a FIRST AID KIT for any issues that would arise.
It's definitely better to have it and not need it rather than need it and not have it.
Also, make sure your coop(s) have a proper amount of VENTILATION. Your chickens will absolutely thank you for it!
