Chances are mate, if you've trained them to keep off your pigeons, they won't nail them in the field, don't tell the dog off for not chasing birds, it's only doing what you want it to do, anyway mate, I wouldn't lose sleep over it, aslong as its game for the quarry you want it for then jobs a goodin.. To be honest I'd prefer a dog that didn't go for feather if I kept pigeons myself, otherwise you could end up losing a few, Atb Dan.
