If the pigeon nest is not disturbed, pigeons will be happy to nest and breed in the same place, which is also their instinctive behavior in nature. So, if you don't mind the existence of pigeons, you can let them continue to live in the pigeon nest at the door. However, if you are afraid of pigeons or your children don't like pigeons at home, or you are worried that pigeon droppings will affect the hygiene at the door, you can consider taking measures to disturb them and let them move away. While avoiding pigeons from over-breeding, we should also try to avoid hurting them.
In short, there is a pigeon cage at the door, and it is necessary to decide whether to intervene or maintain the status quo according to the specific situation. At the same time, please be careful not to harm birds and their proper ecological environment for any behavior.
