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.
Best Answer: It takes 14-16 days for a Zebra Finch egg to hatch! But remember it is not till the bird has laid it full clutch(5-6 eggs) as she will not start to brood till the last egg is laid. Always have a good supply of soaked sprouting seed available for the parents to feed the young.
