I'd say seeking your vets advice is ideal best practice.
Absolutely! However, more often than not, I spot problems with my animals in the evening, and if it's not an emergency, I can often find the answers to my questions via a quick forum search or post. This means I can either save a call to the vet entirely, or can be far more clued up in what I'm saying to them the next morning.
I find it frustrating when someone seeks advice on a forum then does their own thing.
Hmmm, if I always followed all the advice I read on the internet, I'd be dead by now, and so would my animals!
I get your point though, and it IS frustrating when people are told they need to see a vet, but then don't do it or delay the call due to cost or whatever.
However, vets aren't infallible, particularly when it comes to less familiar animals such as poultry. Our vet prescribed us some goose wormer last week with the message "this is all we've got I'm afraid. Let us know if you need more and we'll order it in for you". However, when I got home and read the label I realised that the bottle contained enough to treat eighty geese, rather than the eight I'd asked for. The reason? Decimal point in the wrong place!
