In the UK, a peacock laying season typically spans from March to July. 

A single peacock will breed with up to five peahens, called a harem. A group of peafowl is called a muster.

​

The peacocks with the longest most impressive tails will be seen by the peahens as the most fertile. Peahens ignore a younger male with a shorter tail.

The peacock will display his tail, dance and strut for the peahens who will casually walk past the peacocks until they are ready to mate.

​

Most peahens can start laying eggs at two years old, with their fertility greatly improves by three years old. 

A peahen will usually lay an egg every other day, often in the evening. 

​

Optimising the peafowl breeding season

Remove the eggs regularly so the peahens will continue laying in cycles . The peahens will lay an egg every other day having a break of 10–14 days before starting to lay again. They can lay up to three cycles during the season.

Here's a more detailed look:

• Maturity:

  Peafowl (Peahens, Peacocks) reach sexual maturity and full fertility around three years old. 

• Laying Cycle:

  Peahens lay an egg every other day, usually in the evening. 

• When a peahen is going to lay an egg. Ther wings will look droopy and hang down.

• Breeding Season:

  The breeding season in the UK is generally from March to August, but it can be affected by weather. 

• Nesting:

  Peahens will lay their eggs in small, dug-out depressions on the ground. Ideally you need to provide her with nesting material, straw, sawdust bedding, our peahens like cardboard fruit and veg trays to make their nest in. 

• It is always safer for the Peahen to be inside to incubate her eggs, she is vulnerable to attacks from foxes, rats etc and other peahens will try to share her nest or steal her eggs, causing breakages and inconsistent sitting.
