How Often Do Finches Lay Eggs?

Finches begin producing eggs when they are 6-7 months old. Once a female finch reaches sexual maturity, she is capable of reproducing in any environment. Most finches will not lay eggs if they do not have a partner or if the mating season has passed. 

But one question still remains: How Often Do Finches Lay Eggs?

Most Finches lay eggs between the months of March and August. On average, finches can lay up to three clutches of eggs (each clutch with 2-6 eggs) in one breeding season. But at their maximum potential, they can lay six clutches of eggs in one breeding season.

Finches will typically lay one egg every day until their nest is completely filled, which is usually six eggs. They will re-inhabit the nest after the chicks have flown the nesting box.

House finches are monogamous in their relationships, i.e., one male with one female. Males and females begin looking for partners in the winter, and by the time the mating season arrives, they have formed mating pairs of their own. Even though a breeding couple may produce as many as six clutches of eggs in a single summer, they could only correctly raise up to 3 clutches at a time.

Why do finches keep producing eggs?

Most finch species produce one egg per day, with the exception of a few species. It’s in their natural capability to produce eggs frequently. It is in their genetics. But remember, frequent egg laying led to uterine tiredness along with nutritional inadequacies such as calcium, vitamin E, and selenium deficiency, among other things. So, you must give dietary supplements to your finches during their breeding season.

How do finches lay fertilized eggs?

Finches lay eggs via internal impregnation, which occurs when their egg fertilizes within the female bodies. It appears due to the male depositing his semen in the female bird’s cloaca, which serves as both an entrance for semen and an exit for waste and eggs. The male sperm fertilizes the female finch’s egg, and a tough-shelled small egg develops within the female bird. This thin membrane creates a closed covering around the embryo during development. It protects the embryo and maintains a steady temperature for its development.

What causes finches to lay unfertilized eggs?

Unfertilized or unplanned egg production is a condition that has been seen in pet birds that are kept in captivity. This occurs in most situations because the finch is not intended for mating and begins laying eggs when the male partner is absent. In other instances, the pet parent may be completely uninformed of the bird’s sex or its capacity to lay eggs.

Candling Finches Eggs

Candling is conducted to check the growth and development inside finches’ eggs. Candling also differentiates the fertilized and unfertilized eggs. The egg’s contents will be revealed due to the light during this process. Any crimson veins that may be seen through the shell indicate a healthy egg. A well-developed cavity should allow for the visualization of an outline of a bird within. There will be no hatching of the egg if all you can see is a form with no red lines drawn around it.


The finches typically begin incubating after the third or fourth egg has been deposited.  Afterward, the couple will take turns (usually, depending on the variety) to sit on the egg. Usually, the female takes over at night, and males share incubation duties during the daylight hours. After 13-14 days, the eggs will begin to hatch.  In addition to occasionally turning the eggs, parents maintain high humidity levels by taking a short bath and then returning to the nest.

When is it OK to separate baby finches from their parents?

After 21 days, the baby birds will be able to fly from the nest to the cage and begin to feed themselves. After six weeks, they will start to develop the colors and feathers of their adult selves. At that time, you should separate the tiny finches from their parents.

Reasons: Why Finches Eggs Do not Hatch?

There are a variety of reasons why eggs may not hatch, including:

·   When there are no male finches available to fertilize the eggs, females will occasionally lay unfertilized eggs (which never hatch)

·   Sometimes a couple of immature finches may be ineffective in their mating efforts; in that condition, females lay unfertilized eggs.

·   Occasionally, one or more eggs in a clutch will fail to hatch due to the failure of an unborn chick to grow appropriately or because that specific egg managed to prevent fertilization.

·   In some cases, a bird may fail to properly care for her eggs, resulting in their not hatching correctly – this is somewhat typical when she is young and raising her first clutch of eggs.

·   The egg may have fallen directly to the ground – either from a perch or over the edge of a confined nesting box – in which case it will have been’ scrambled’ by the predator.

·   The male bird may be sterile.

·   Overcrowding and stress in an aviary or birdhouse may be the source of the problem.

·   If eggs fail to hatch because the shells are too soft, it’s an indication that the hen didn’t obtain enough calcium throughout her pregnancy


Is it possible for female birds to give eggs without the presence of a male?

Egg-production in birds is a natural and continuous process. So, female birds can produce eggs even if no male is present in the nesting area.  Even while egg production can occur in any avian breed, it is most prevalent in budgies, cockatiels, lovebirds, and finches, among other species.

Is it true that finches leave their eggs?

Finches are pretty good at concealing their vulnerability; it’s a primal instinct. Finches that are sick will be unable to provide adequate care for their clutch. They may simply toss a few eggs or chicks to relieve themselves of the stress of raising a big family. Alternatively, they may quit the whole clutch and utilize the time to attend to their personal requirements.

What can you do with Finch eggs?

It is recommended that you leave the eggs alone and let the parent birds take care of them. The only thing to remember is to provide new bird parents with lots of food in their cage so that they may feed their young (after their hatching)

Tip: Allow the birds to build their own nests and care for the eggs independently.

What is the maximum amount of time finch eggs may be left unattended?

Once the incubation process has begun, it should not be interrupted (or the embryos will die). To allow the parent birds to stretch their wings or take a break to feed and drink, the eggs can be left unattended for short periods of time (about 12-25 minutes).

Do house finches tend to come back to the same nest over and over again? 

Yes, they return and re-use their nests for the next generation of chicks.

Is it possible to relocate finch eggs?

No, you should not relocate them and should simply let them alone. If you relocate the eggs, the birds will no longer sit on them.

Hello, I am Rick Matthews, I have helped raise 100's of pets in my life living with my Father who while we did not live on a farm, raised all sorts of animals to sell them to families. We had so many different pets we all quickly became experts intending to them and helping them stay healthy. Back then we did not have the internet to look up thing on how to take care of their kids. As my kids got older, they wanted pets and of course, I did not want to have as many as we did when I was a child, but wanted to share my experiences. Many of these articles are written to help educate families on what to expect when looking to get a new pet for their children.
