Why Did My Single Pet Bird Lay an Egg?

broodingIt can be quite a shock to a bird owner when a single female bird lays an egg. What causes single birds to lay eggs? Will the egg be fertile? Does laying these eggs mean that your bird has a health problem? Find out the answers to these questions below!

What Causes a Single Bird to Lay an Egg?

Just like birds in the wild, your pet bird has breeding hormones. In the wild, these hormones are only activated during certain times of the year when breeding conditions are favorable. In captivity, birds experience favorable conditions year round. This means that females may start laying eggs and male birds may display aggressive behaviors, as is typical during breeding seasons.

In particular, the following conditions encourage this egg-laying behavior:

  • Exposure to artificial light for extended periods of time, mimicking an increase in daylight hours
  • A warm indoor environment
  • Bonding with an object or toy that the bird identifies as a mate
  • Plentiful food and water
  • Shreddable materials that are perfect for building a nest

Signs Your Female Bird May Lay an Egg

Once you know what to look for, you can be prepared for finding an egg in the cage in the future. Before a female lays an egg, it will feel heavier, and the lower abdomen will appear larger and be firm to the touch. Your bird will consume more water and may begin shredding materials in the cage to build a nest. Finally, the bird’s droppings will get larger until they stop briefly during the binding of the egg.

Is the Egg Fertile?

The egg your single female bird lays is not fertile as long as she has not been around a male bird. There’s no need to worry about a baby bird hatching, but your bird may need to nest with the egg for a while to stop the egg-laying cycle.

Does Egg Laying Pose Health Problems?

Laying an occasional egg does not indicate a serious problem. However, removing the egg too quickly from the nest may cause the bird to enter another reproductive cycle to replace it. Laying eggs takes a lot out of a bird. They’re usually unwilling to leave the cage for feedings, may experience calcium deficiencies and have poor health in general. So, while one egg isn’t a big deal, laying eggs many times a year is something you should try to avoid. Ask your vet’s advice about how long you should let your bird nest with the egg before removing it to stop the reproductive cycle. If your bird continues to lay eggs, a visit to the vet may be necessary to get medications to control the hormones.
