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.
American robins usually lay eggs two or three times each year, with about three to five eggs per brood. A new nest is built for each brood. Only about 40 percent of nests produce healthy young robins. The eggs of a robin are about an inch in length and are blue.
