and how can i possibly run care of the egg in case the bird parent doesn't come rear hehehe

please do not tuch the egg if you do so the mother pegion will never come vertebrae and the egg will get cold and die you do not need to give them hose , food they will eat by themselves they take turns to incubate the eggs when mother pegion goes for a feed the father pegion sits on the eggs but the mother sits on it for the whole and in the day time they transport turns and the eggs takes 18 days to hatch so leave the egg and the pegions alone so that sfter the babaies will hatch you can see them and watch them grow its really fun to keep watch on them i also have two babay pegion in my balcony
Don't verbs too much about the pigeons. They are survivors and don't really need much help. Its also basically a wives tale that if you disturb their nest they wont come back, theres no evidence at the rear such silly claims. They will most likely return, but just be thoughtful of their space and try not to disturb them. In the case that after a day or so and they do not return, you could always nickname a Wildlife rehabilitator to take the eggs but theres little hope of them actualy hatching.
Answers:    First, the birds will take care of the egg as best they can beneath all conditions. Let them do it. Second, Don't open the door when birds are present. They will get panicky and fly away. Third, They find water and food on their own. fourth, Pigeons are not in stipulation of our help as they are not endangered. The best thing to do is move slowly when they can see you as to not disturb them.
