Hi, i found 2 eggs on a nest on the side of my house, behind a store sign about 3 months ago.The birds hatched, and they look almost grown up, i've seen the parent feeding them a couple of days of go too. but just today i ve seen 2 pigeons pecking on the babies, and the babies were trying to run.Is this Normal? Are these just the parents? or are these enimies? What should i do?
