I raise pigeons myself and you should not throw the life of a pigeon away even if it is just a bird they have familys to raise just like us humans so you should leave the eggs alone the squabs{baby pigeons} will leave the nest in about a month it should atleast be intresting to watch them grow i would love a pair of pigeons to lay eggs at my house ofcourse lol and you should not chase the mother away from the nest because then the eggs will grow cold and die and that would be a lost child for the mother pigeon so you shoold just leave them nest there with out disturbing tham at all and when they leave put up some owl statues and that should keep no more pigeons from comming on your balcony.
