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.
Since a female flea can lay about 40 eggs per day, a few case studies have shown that for each flea you find, there are an estimated 120 eggs (or a further stage of the flea development cycle) around your home (see photo of flea eggs above) or garden.
