I’ll bet you could make a fortune running drugs into CanadaNPIP is not a thing here in Canada, and vax of backyard flocks also not a thing, next to impossible to get them for your poultry here. Only factory farms can get hold of any vax, and generally do not even bother as they are inside, broilers are processed at 6-8 weeks and layers are processed at 1.5 yrs just before they do their first moult.
Breeders of fancy birds don’t have access to vax unless they somehow get hold of it, and use of gender DNA testing is generally not done. People are not generally going to pay the expense of getting a day old chook for $50 to 100 - average price here is about $12 - spending more than $20 is unusual.
