How do you know if the canary egg is from the boy bird?

Answer 1

One way is to hold the canary on its back (as in, hold the canary in the palm of your hand where its tummy is facing towards you) and blow lightly/gently near its private area. If you see a small thing sticking up, then it's obviously a male. If you don't see one, then it's a female. Sometimes, however, it may be difficult to see what you want to see/find.

You can not go by singing because females can mimic males.

Answer 2

When the canary is still in its nest and the feathers have just come in, and their wings still look like sticks, tap the nest with your finger, (not the chicks) and the females will pop their heads up and look at you, and the males will stick their heads down and their behinds up at you.

When the canary is an adult it is a little harder to tell but the only way I know of is if the canary sings, its usually a male, and of coarse, the female will lay an egg.

Answer 3

A male canary has a voice that can sing in a nice tempo a female cannot sing.

Answer 4

Male birds cannot lay eggs.
