Honestly I would say you are at a better time than someone in their mid thirties with toddlers running around.
However the reality is this whether you are 20, 35, 50, or 70 you can obtain and train a bird dog. Will it always be a vc? No but it will hunt birds and it will hunt them well.
Obedience training following either a book, podcast, or you tube standing stone video series is free (or close to free). That is the base of a good bird dog. You can train a dog with birds if you live somewhere that has birds you are in luck if you don't that will be the most expensive part.
IF you have property or friends with property put a recall pen up and raise chukars or quail. If not you will pay 10-15 bucks a chukar or quail. Reality is though you can help the dog figure it out with 50 birds or less.
