Trying to dig a 12 to 30 foot long trench manually will be a nightmare. My recommendation is to bite the bullet and rent a trencher to do the work for you. Even at 12 inches, your work is cut out for you, but 36 inches is really deep.
After the two-month incubation period, the turtle hatchlings all dig out of their nest at the same time, a process that can take several days. As a group, they then leave their nest at night and head directly for the sea. This first trek imprints their home beach into the hatchlings.
6. Record the day and how many eggs you've incubated on a calendar. You should be able to estimate your hatch date based on average incubation times for the bird species you want to hatch. For example, chicken eggs typically take 21 days to hatch, whereas many duck varieties and peafowl may take 28 days.7. Turn the eggs at least three times daily.andle the eggs after 7 to 10 days. Candling the eggs is when you use a light source to view how much space the embryo occupies within an egg. After 7 to 10 days, you should see development of the embryo.
