Why did President Truman ask Congress to give financial aid to Greece and Turkey?
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.
This varies somewhat depending on the type of finch. Usually around 14 days of incubation, but a general range can span 12-18 days. Note that incubation does not begin until the parents start sitting, which frequently will not happen until the 3rd or 4th egg is laid, or sometimes the entire clutch. DX Â· 7 years ago.
