How long will a pigeon roost after it has layed its eggs?

Question

A couple of pigeons decided to have their babies on my balcony and I was wondering how long they will stay after the eggs hatch. I read that it takes about 17 days to hatch and the babies need to be taken care of for two to three weeks after. Will they be there the whole time? They already made a hot mess and we don't want to be charged for excessive pigeon c**p out there when we end up moving out.

Answer 1

The babies will wean at about 35 days.  When they do, you can just take a hose to what left and it will wash off with almost no residue at all.

Answer 2

they will stay until the babies learn to fly.
