How to Tell If Quail Eggs Are Fertile

Raising quails is a fast-growing and fun hobby for many new poultry enthusiasts. To hatch your quail, if you own a male, start with eggs your own hens lay, or purchase them from a qualified hatchery. According to Melvin L. Hamre, Extension Poultry Specialist from the University of Minnesota, eggs sold in stores tend to be infertile. Eggs can be checked for viability after five days of incubation through a process called candling. Taking a quick peek with this method ensures embryos are developing and saves time waiting for a bad batch to hatch.

Instructions

    • 1
      Wood candling box.

      Drill a 1-inch hole at one end of the wood box. Fit the end of the lightbulb in the hole. The bulb part will be inside the box and the end will stick outside to hook to an electric source.

      Wrap the felt cloth around any light leaks around the egg in the box to clearly view the contents.

    • 3

      Use a flashlight in a dark room as an alternative. Hold the fat end of the egg up to the light. You should be able to see inside the egg. Lighter-colored eggs are easier to view. The embryo will show as a light red tint inside the egg. As the chick grows and takes up more room in the eggshell, the shadow will be darker.

      Remove any eggs from the incubator that view clear or show no signs of continued development after 10 days.
