My worry with baiting is that it might be looked at as "unethical" and/or "bad practice" which, may lead to the banning of woodpidgeon shooting. If this practice becomes a common method, the anti-shooting campaigners will be given more power and more excuses. I feel it is up to us, shooters, to decide whether it should be banned or allowed( I do not like such practice myself) and force the issue to be clarified.
See links below for info. There is no clear evidence of what is allowed and what is not.
