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.
In the spring, the female will lay about 20 eggs which she will setâ¦ on both day and night until the eggs hatch about 28 days later.   I am not joking, but if you want to use an incubator there are many sites on the web to tell you how and where to get the eggs.
