I think most people would take their pet to a vet-be it a $5 chicken or not-IF they were available. If it were a free puppy, people would be taking it to a vet for needles, preventative medicine, etc. I don't think the cost would be a huge factor if it were a pet. Not in Canada, nor in the US. I really think it's a matter of finding a vet, within a decent distance, that will treat a chicken.
Kelly I know you understand this now. I have many friends across the European countries and we constantly talk about vetting, but, Canada and US just don't have the access. Personally, if I had a PET chicken, it would be far safer to have it vetted than me give it a needle, set a leg, diagnos a disease, etc. Even a lot of the time we have the same problem no matter the animal. Sadly, it is the access we don't have. Many, many birds die (not just birds, but many farm animals as well) because of something that could be treatable if we had been able to access a proper farm vet.
It's a very, very sad case over here.
