If you want to learn then natural will tell you a lot about the pigeons behaviour during racing and breeding. I would think that 99% of the fanciers on here would have started wae some kind of natural system. If you want to compete from sprint/middle races then widowhood(IMO) is the way to go bad as yer only startin then will you be expectin tae be at the front straight off? On the other hand, if yer like me , the competitive urge will mean you will be tryin!! The widow system must be followed religiously ie. Routine of exercise, feeding correct, hens kept content without laying or pairing and condition time watched closely.
