When a chicken is a setter, it means that it will hatch its eggs. The majority of chicken breeds will occasionally go broody, meaning they will set their eggs and try to hatch them. Setter breeds frequently go broody, such as Orpingtons and Cochins. High-production breeds like Rhode Island Reds and Leghorns seldom go broody and are considered non-setters. In the context of poultry hatcheries, setters are used to incubate eggs, while hatchers are used to hatch the eggs. Optimal utilization in a hatchery is achieved with a ratio of 6 setters for every hatcher.

A setter is a hen that frequently goes broody
A "setter", in the context of chickens, refers to a hen that frequently goes "broody". When a hen goes broody, it means that they want to be a mother and will set their eggs and try to hatch them. This is done by sitting on the eggs. While some breeds of chicken will seldom go broody, such as Rhode Island Reds and Leghorns, other breeds like Orpingtons and Cochins are known for frequently displaying this behaviour.
The term "setter" is also used in the context of poultry hatcheries, where it refers to the process of incubating eggs. In this setting, setters are machines used to incubate eggs, while "hatchers" are machines used to hatch the eggs. The relationship between setters and hatchers is crucial, as they are interdependent, and the proper functioning of one directly affects the other.
To optimise the utilisation of a hatchery, it is recommended to have six setters for every hatcher, and it is important that the eggs in each setter are of the same age and from the same flock. Additionally, the overall temperature in a setter machine should decline from day 0 to day 16 by 1.0-1.8 °F. This decline needs to be higher when there is more heat produced by the embryos, lower air speed, and lower heat capacity of the air.
Furthermore, high moisture loss during storage can be detrimental to the eggs, although it can be compensated for by higher humidity during incubation. Modern gas-tight single-stage incubators address this issue by maintaining very high humidity during the first days of incubation, when ventilation is usually kept closed.

Broody hens want to be mothers and will sit on and hatch their eggs
When a hen goes broody, it means she wants to be a mother and will sit on and hatch her eggs. This behaviour is common in chicken breeds like Orpingtons and cochins, which are known as "setters". The term "setter" refers to a hen that frequently exhibits broody behaviour, indicating her desire to become a mother.
Broody hens will sit on their eggs, keeping them warm and protected during the incubation period. This maternal instinct is a natural part of their reproductive cycle, and most chicken breeds will occasionally display this behaviour. However, setters are known for their consistent broodiness. While some may view this as a nuisance, especially if they are not interested in hatching eggs at home, others appreciate the personality traits of these breeds.
During the incubation process, setters play a crucial role in maintaining the optimal temperature for egg development. The overall temperature should gradually decrease from day 0 to day 16, with the specific temperature range depending on various factors such as egg size, fertility, oxygen availability, and the design of the incubator. Modern incubators, also known as setters, provide controlled environments for egg incubation, ensuring uniform warming and disinfection.
To optimize the incubation process, it is important to fill the incubator completely with eggs of the same age and from the same flock. If the setter is not full, trolleys can be "balanced" by leaving the top two and bottom two trays empty while filling the remaining spaces with empty trays. This ensures proper airflow, which is essential for successful incubation.
Additionally, humidity plays a significant role in the incubation process. High moisture loss during storage can be detrimental, but it can be compensated for by increasing humidity during incubation. Modern gas-tight single-stage incubators maintain high humidity during the initial days, followed by lower humidity and increased moisture loss during the final week in the setter.

Chicken setters are interdependent with hatchers, which are used to hatch eggs
In the context of chickens, a "setter" is a hen that frequently goes broody and hatches her eggs. The term "broody" refers to a hen's maternal instinct to sit on her eggs and become a mother. While most chicken breeds will occasionally exhibit broody behaviour, certain breeds, such as Orpingtons and Cochins, are known for their propensity to go broody and are considered setters.
Chicken setters play a crucial role in the process of hatching eggs, and they are closely linked with hatchers, which are machines used in poultry hatcheries. The relationship between setters and hatchers is one of interdependence, where the proper functioning of one directly impacts the other. Setters are used to incubate eggs, maintaining a specific temperature and humidity to create optimal conditions for embryo development. The setter phase typically lasts for 18 days, during which the overall temperature gradually decreases from day 0 to day 16.
Hatchers, on the other hand, are used to hatch the eggs after the incubation period in the setter. The hatcher phase is shorter, usually lasting only 3 days. To ensure optimal utilization of the hatchery, the ratio of setters to hatchers is typically 6 to 1. This means that for every hatcher, there should be six setters of the same size. For example, six setters of a particular size may require three hatchers of a smaller size to maintain the proper ratio.
The size of a poultry hatchery is determined by various factors, including the target market, breed type, production cycle, and budget. If the target market is large, a larger hatchery is needed to meet the demand. The type of breed also impacts the hatchery size, as different breeds have specific requirements for incubation and hatching. The production cycle refers to the time needed for both egg incubation and the growth of chickens for slaughter.
In summary, chicken setters and hatchers are interdependent components of a poultry hatchery. While setters are responsible for incubating eggs, hatchers are used to complete the hatching process. The proper functioning and coordination of these two processes are essential to ensure successful chick hatching and maintain optimal hatchery operations.

Optimal utilisation in a hatchery requires 6 setters for each hatcher
In the context of chickens, a "setter" is a hen that hatches her eggs. The term is typically used to describe a breed or specific hen that frequently exhibits broody behaviour, which is when a hen wants to be a mother and will sit on her eggs.
In a poultry hatchery, setters and hatchers are the two primary components. Setters are used to incubate eggs, while hatchers are used to hatch them. Optimal utilisation in a hatchery requires a ratio of 6 setters for each hatcher. This is because setters run for 18 days, while hatchers run for 3 days, resulting in a 6-to-1 relationship between the two.
The size of a hatchery is influenced by various factors, including the target market, breed type, production cycle, and budget. The target market plays a crucial role, with larger markets requiring a larger hatchery to meet demand. Breed type is also important, as different breeds have specific requirements for incubation and hatching. The production cycle refers to the time needed for both egg incubation and the growth of chickens for slaughter. A longer production cycle does not necessitate a larger hatchery. Budget is a critical factor, with the size of the hatchery directly proportional to the budget available.
To optimise the utilisation of setters and hatchers, certain operational considerations should be made. For example, incubators produce the best results when they are full, and the eggs are of the same age and from the same flock. If the setter is not full, trolleys should be "balanced" to ensure proper airflow. Additionally, the overall temperature in the setter should gradually decline from day 0 to day 16, with the specific temperature range depending on various factors such as egg size, fertility, oxygen availability, incubator model, and air humidity. Modern gas-tight single-stage incubators maintain high humidity during the first days of incubation, resulting in relatively lower moisture loss for the eggs.

Setter incubators should be full, with eggs of the same age and from the same flock
In the context of chickens, a "setter" is a hen that frequently goes broody, meaning she wants to be a mother and will set her eggs and try to hatch them. Orpingtons and cochins are examples of chicken breeds that are typically setters.
Incubators are machines used in the process of hatching chicken eggs. Setter incubators are used to incubate eggs, while hatchers are used to hatch the eggs. Optimal utilization of a hatchery is achieved when there are six setters for every hatcher, and these setters should be of the same size. To ensure the proper functioning of the hatchery, it is crucial to maintain a balanced ratio between setters and hatchers.
While it is ideal to have eggs of the same age and flock in a setter incubator, it is not always possible. In such cases, compromises must be made. For example, if the setter is not full, trolleys should be "balanced" to ensure proper airflow. This can be achieved by leaving the top two and bottom two trays empty while filling the remaining spaces with empty trays. Alternatively, eggs from another flock or storage time can be used to fill the setter, but it is important to seek advice from the machine manufacturer to avoid any problems or disappointing results.
