Come to think of it, why do you never see baby pigeons?
Because they haven't left the nest you moron.

Birds and ReproductionBirds reproduce by sexual reproduction. Many birds have courtship rituals. Male and female birds from many bird species develop pair bonds. They actually remain with one another throughout the reproductive season. The male bird's sexual organs consist of paired testes. The female bird's sexual organs consist of only a left ovary and oviduct. This left ovary and oviduct is the only functional ovary that the female birds have.
The Male Bird's SpermDuring sexual reproduction, the male bird's sperm passes out of the testis and into the vas deferens. The vas deferens is a duct that expands near the cloaca into a storage organ. The cloaca is a common chamber that receives digestive wastes and urogenital products such as urine and gametes. This is common in most vertebrates.
Coitus and BirdsSome male birds actually have a sexual organ much like a penis. Some of these include anseriformes, the cracidae and the tinamidae. The act of coitus generally may only last a few seconds with birds. However, the length of coitus depends on the species of the bird. During coitus, the male is generally mounted on top of the female's back.
The Laying of EggsOnce the male bird deposits his semen into the female bird's cloaca, the female birds lay sets of eggs. These eggs are referred to as clutches. The eggs are laid in distinct groupings in plainly distinct nests. These nests can vary from formations of simple grazes in the ground to very highly structured nests.
