is it possible to trap feral pigeons out of old buildings?
i think i read somewhere that all pigeons can be taught to "home"
just leave'em in the coop for a few weeks and you start by taking them 100 yds away and toss'em,than increase the distance
probably oughta research it
one falconer i know would just go in an old barn at night and grab them off the roost,by hand
there was also something about dosing the birds with medicine( its cheap) when they're caught wild.
cant remember,chickens and pigeons can carry diseases ,you might want to research it
the doves are protected by the same treaty as ducks and geese
good luck
