Actually checking the nest for the number of eggs while a finch is sitting on them can cause nest abandonment. After mating, a female finch can store sperm in her reproductive tract for up to 16 days. Female finches generally lay an egg every day, commencing between five and seven days after breeding. The average clutch consists of four to six eggs, although the overall number varies from three to eight.
The number of eggs a female bird will lay before her clutch is complete depends on several factors: Species: For example, an Eastern Bluebird may lay 4-7 eggs. (Four or five is most common.) A Black-capped Chickadee typically lays 6-8 per clutch, with as many as 13 reported. Some species (called determinate egg layers) will not lay extra eggs in response to egg removal (simulating removal of eggs by a predator), or do not stop laying eggs if eggs are added to their nest.
