What is the saying that pigeons lay eggs outside the balcony?

Generally speaking, you can make a nest, a paper box or anything. Put pigeon eggs in a conspicuous position, and pigeons will hatch in their nests.

As for the other pigeon, the pigeon takes turns incubating eggs. This one hatches eggs, and the other one goes out to look for food. You can sprinkle some corn kernels on the balcony, and it will come and eat by itself. Try not to go near them when they are eating, so they will guard against you.

It takes about twenty-four to twenty-eight days for a pigeon to change from an egg to a young bird. After hatching, the adult birds will feed some pigeon essence to the young birds.

Ha ha!
