What You'll Learn
Lighting is crucial for growth and development
Lighting is crucial for the growth and development of chicks. While natural sunlight is essential, artificial lighting is often necessary, especially during the early stages of a chick's life.
Natural sunlight is a rich source of vitamin D3, which is crucial for calcium absorption and healthy bone development in chicks. Exposure to sunlight during the day and darkness at night helps establish a regular rest and activity pattern, leading to better overall health.
During the winter months or in controlled indoor environments, artificial lighting can supplement natural sunlight to ensure chicks receive sufficient light exposure. Chicken coop lights, heat lamps, and brooder heating plates are commonly used to provide artificial lighting for chicks.
Maintaining consistent lighting cycles is vital for chick wellbeing. A typical lighting schedule includes 12 to 14 hours of light followed by 8 to 10 hours of darkness, with adjustments made as the chicks mature. Using timers with artificial lighting sources can help automate this process and ensure a consistent lighting schedule.
Preliminary studies have shown that while 24 hours of light may result in slightly higher weights during the early days of a chick's life, there is no significant difference in weight, feed conversion, or mortality rates between chicks provided with a dark period and those kept under constant light. Therefore, it is generally recommended to provide chicks with a period of darkness to establish a healthy day-night cycle.

Natural light is important for vitamin D3
Chickens, like all creatures, are born with a 24-hour circadian clock. This circadian rhythm can be observed in the feeding and drinking activity of chicks, which tends to be higher during the day than at night. Providing a dark period is important for the health of chicks, as they need to sleep through the night without light.
Natural light is important for the growth and development of chicks, and they require vitamin D3 for calcium absorption, which is crucial for healthy bone development. Natural sunlight is a rich source of vitamin D3, and chicks can manufacture their own vitamin D3 when exposed to sunlight. However, during winter or in places with limited sunlight, artificial lighting can be used to supplement natural light and ensure chicks receive sufficient exposure.
Vitamin D3 is one of the two main forms of vitamin D, the other being vitamin D2. Vitamin D3 occurs naturally in certain foods, such as salmon, tuna, mackerel, beef, liver, and egg yolks. However, these foods are typically not consumed in large enough quantities to meet the body's vitamin D3 requirements. Therefore, other foods such as milk, cereal, and some orange juices are fortified with vitamins D2 and D3. Additionally, the body can produce vitamin D3 through exposure to sunlight, specifically ultraviolet B (UVB) rays.
While natural sunlight is a significant source of vitamin D3, recent research has shown that ultraviolet (UV) LED lights may be even more effective in producing vitamin D3. A study by Tyler Kalajian and his team found that skin samples exposed to RayVio's 293nm UV LED light produced more than twice as much vitamin D3 in half a minute as samples exposed to 32.5 minutes of sunlight. This suggests that UV LED lights could be a viable alternative for vitamin D3 production, especially in regions with limited sunlight.
In summary, natural light is important for vitamin D3 production in chicks, and they require a proper day-night cycle for their overall health and well-being. While natural sunlight is a rich source of vitamin D3, artificial lighting can be used to supplement it, and in certain cases, UV LED lights may offer an even more efficient means of vitamin D3 production.

Artificial lighting is necessary during winter
When raising chicks, it is crucial to understand their lighting needs for their growth and development. While natural sunlight is essential, artificial lighting is often necessary, especially during the early stages and winter months.
Maintaining consistent lighting cycles is vital for baby chicks' well-being. Typically, a lighting schedule of 12 to 14 hours of light followed by 8 to 10 hours of darkness is recommended. Using a timer with chicken coop lights or heat lamps ensures an automated and consistent lighting schedule, which is crucial for their growth, development, and overall health.
During the winter, natural sunlight may not provide sufficient lighting for chicks, especially in regions with shorter daylight hours. In such cases, artificial lighting can supplement the natural light to ensure the chicks receive adequate exposure. This is particularly important for their bone development as they require vitamin D3, which their bodies absorb from sunlight.
Additionally, providing adequate lighting during the winter can help regulate the chicks' circadian rhythm, affecting their behaviour, growth rate, and overall health. While some sources suggest that chicks benefit from 24 hours of light, studies have shown that they still exhibit a natural day-night cycle, drinking and eating more during the day than at night. Therefore, it is essential to provide a period of darkness to allow them to rest and synchronise their internal clocks.
In conclusion, artificial lighting is necessary for chicks during the winter to ensure they receive sufficient lighting for their health and development. However, it is crucial to balance this with periods of darkness to allow for a natural day-night cycle and adequate rest.

Red bulbs allow for a natural day/night cycle
It is important to understand the lighting needs of chicks for their growth and development. While natural sunlight is crucial, artificial lighting is often necessary, especially during the early stages.
Chicks require a proper day-night cycle, and exposure to appropriate lighting helps establish a regular rest and activity pattern, leading to better sleep and overall health. They require vitamin D3 for calcium absorption, which is crucial for healthy bone development, and natural sunlight is a rich source of vitamin D3. However, artificial lighting can supplement this, especially during the winter months when sunlight is limited.
Red bulbs are recommended because they are not as bright as clear ones, allowing chicks to have a natural day-night cycle. Chicks need darkness to sleep, and bright white light would keep them awake. Red bulbs also discourage chicks from picking at each other. Reptile bulbs are not hot enough, and 250-watt varieties are most recommended.
Preliminary studies have shown that chicks tend to drink and eat more during the day than at night, even when provided with 24 hours of light. This indicates that they are looking for a period of low activity or a dark period. Therefore, it is recommended to provide chicks with a four-hour dark period each day.

Chicks need a dark period to sleep
Chicks do not need to be provided with light 24 hours a day. In fact, they benefit from a period of darkness each day.
Chicks, like all creatures, have a 24-hour circadian clock. They tend to eat and drink more during the day than at night, even when provided with 24-hour lighting. This suggests that they are looking for a period of low activity each day—a dark period.
A preliminary study at the University of Georgia Poultry Research Center found that chicks given a four-hour period of darkness during brooding had improved uniformity compared to those who did not. While there was no significant difference in weight between the two groups by Day 14, the chicks with a dark period weighed less on Days 3 and 7. Feed conversion and mortality were also not affected by the introduction of a dark period.
To ensure your chicks are getting adequate rest and to promote their overall health, it is recommended that they get 8 to 10 hours of darkness each night. This will allow them to sleep through the night without eating or drinking, which is beneficial for their overall health and well-being.
