Understand the Pigeon Life Cycle and Take Action Early Before They Multiply

A pair of pigeons can turn into a flock of 20 in less than a year. This isn’t an exaggeration but a result of their short and continuous breeding cycle. Many people ignore the sight of just a couple of pigeons, not realizing it's a missed chance to prevent a much bigger problem. It is always easier to deal with two pigeons than a whole flock. Understanding their growth timeline is the key to stopping the cycle early and keeping your property clean and bird-free for good.

A Speedy 18-Day Life Cycle: From Eggs to a Bigger Problem

The issue doesn’t stop at the eggs being laid. The 18-day incubation period is only the beginning of a rapidly growing problem. Here’s the full timeline from eggs to infestation:

• Phase 1: Before the 18-Day Countdown (Settling In)
  A pigeon pair searches for a safe, undisturbed spot to nest. Condo balconies, AC compressor units, and building crevices are ideal. They begin collecting twigs, leaves, and debris to build a rough nest. The female lays 1 to 2 eggs, starting the 18-day countdown.
• Phase 2: During the 18 Days (Incubation Period)
  The parent pigeons take turns sitting on the eggs, meaning at least one is always present. The balcony becomes their territory. Daily droppings accumulate around the nest, and chirping noises begin. Even before hatching, hygiene problems and disturbance start to appear.
• Phase 3: Around Day 18 – Problem Doubles
  The eggs hatch. Now there are four birds instead of two. The parents make more trips in and out to feed the chicks, bringing in more germs. Mess and noise increase significantly.
• Phase 4: After Day 18 – Escalating Problem
  The chicks grow quickly, start feathering, and begin to defecate. After about a month, they can fly and feed themselves but usually remain in the same area. The parents may also start another 18-day cycle. Soon, the original pair and their chicks become a larger group occupying your space.

This rapid cycle means one pair can add two more birds every month. From two to four, six, eight and so on — the numbers rise fast.

Seeing two pigeon eggs today means you're on the brink of a much larger problem. Acting early is critical.

Why These 18 Days Matter for Condo Residents

In a small condo space, 18 days make the difference between easy prevention and difficult infestation. Here’s how things compare:

• Before Day 18 (Eggs Not Hatched)
  Only two adults, a nest, and some limited mess. Cleanup is manageable. The birds are not yet bonded with chicks, so it’s easier to deter them. Intervention is more likely to succeed.
• After Day 18 (Chicks Hatched)
  Now it's a family. There is more activity, more mess, and more germs. Chicks defecate constantly. Parents go in and out more frequently, increasing contamination risks. They become more aggressive and harder to deal with. Once they successfully raise chicks there, they register your space as home and will return. Some people also feel bad removing chicks, which lets the problem grow.

These 18 days are not for observation. They are your best chance to act before your balcony turns into a permanent pigeon colony.

Why Waiting Doesn’t Work

Telling yourself "I’ll deal with it later" or thinking they'll go away is the worst mistake. Your silence tells them your space is safe. They settle in and multiply. From two birds, you'll have four, then eight, with waste building up. Their acidic droppings can damage paint, floors, and even air conditioning units.

At that stage, cleanup is harder and more expensive. Simple deterrents won’t work anymore. You may need professional deep cleaning and long-term deterrents. Waiting turns a small issue into a long-term crisis.
