Testing Eggs.

On the seventh or eighth day test the eggs, and remove the infertile ones, which are then good to eat, or to keep to feed the chicks with, use a round tin about 4in. in diameter and 4in. long, one end covered with thick black cloth, in which a hole is cut in the centre to admit the large end of an egg. Place in the position shown in the plate, close to a bright lamp. The fertile ones show a red streak or spot; the infertile ones are clear, like a new-laid egg.

Practice will enable one to tell the eggs that contain dead chicks lates on, by the difference in their appearance from the others.

Return the eggs to the hen or incubator as quickly as possible.
