What are used layers in poultry?

It seems you're asking about the different types of layers used in poultry farming. Here's a breakdown:

Layers are hens specifically bred for egg production. There are two main categories:

1. Commercial Layers:

* White Leghorn: The most popular breed worldwide. Known for high egg production, white plumage, and good egg size.

* Rhode Island Red: A dual-purpose breed, meaning they are good for both egg production and meat. Known for their reddish-brown plumage and good egg production.

* Brown Leghorn: Similar to white leghorns, but with brown plumage.

* Lohmann Brown: A commercial hybrid known for its high egg production and brown shell eggs.

* ISA Brown: Another popular commercial hybrid known for its high egg production and brown shell eggs.

* Hy-Line Brown: Another high-producing hybrid with brown shell eggs.

2. Heritage Layers:

* Ameraucana: Known for their blue egg shells and fluffy beards.

* Buff Orpington: A docile breed known for their golden plumage and good egg production.

* Plymouth Rock: A dual-purpose breed, known for their black or white plumage and good egg production.

* Australorp: A black breed known for its high egg production.

* Wyandotte: A dual-purpose breed, known for their colorful plumage and good egg production.

Choosing the Right Layer:

The best layer breed for you depends on your needs and preferences. Consider factors like:

* Egg production: How many eggs do you need?

* Egg color: Do you prefer white or brown eggs?

* Temperament: How important is a docile breed?

* Climate: Some breeds are better suited to certain climates.

* Space: How much space do you have for your chickens?

Note: The terms "layer" and "hen" are often used interchangeably, but technically a hen is any female chicken, while a layer is a hen specifically bred for egg production.
