What You'll Learn
Insulation and ventilation
When building a chicken coop in Alaska, insulation and ventilation are critical considerations. Firstly, insulation is essential to retain heat within the coop during the frigid Alaskan winters. One chicken generates as much heat as a 100-watt light bulb, so adequate insulation can help maintain a comfortable temperature for your flock. The floor, walls, and roof of the coop should all be insulated. Rigid insulation boards can be placed between floor joists, with spray foam insulation used to fill any gaps. Vapor barriers are also recommended to prevent moisture accumulation, which can lead to rot.
It is important to note that while insulation is crucial, proper ventilation is equally vital. Controllable ventilation allows humidity to escape, ensuring the air inside the coop remains fresh and healthy for the chickens. Passive Hi-Lo ventilation systems are recommended, with insulation kept back from the vents by a few inches. This type of ventilation system allows for natural airflow, helping to regulate the temperature and prevent the buildup of ammonia gas from chicken waste, which can be harmful to the birds.
Windows can also aid in ventilation and should be positioned to take advantage of solar radiation, providing natural light and warmth during the day. Double-pane windows can help retain heat, and the direction they face should be considered during the design phase. South-facing windows, for example, will maximize sunlight exposure.
Additionally, the shape of the roof can impact ventilation and heat retention. A peaked roof helps prevent snow accumulation, reducing the weight load and the risk of collapse. It is also advisable to plan for a heavy snow load, ensuring the roof structure can withstand the weight of snow and that the coop remains well-ventilated even when snow-covered.
Finally, it is worth noting that while insulation and ventilation are essential, so is ensuring the coop is sealed to prevent predators from entering. Vents and other openings should be covered with screens or wire mesh to keep out unwanted visitors, such as weasels, which are a common threat to chickens in Alaska.

Predator-proofing
Chicken predators come in many shapes and sizes, from raccoons, skunks, and opossums to hawks, owls, eagles, and even neighbourhood dogs. Therefore, it is important to take measures to ensure your chicken coop is predator-proof. Here are some ways to do that:
Research Common Predators in Your Area
Determine the types of predators in your region to understand the specific threats your chickens face. This will help you design the most effective predator-proofing strategies. For instance, if you have burrowing predators in your area, you may want to bury wire fencing around the coop's perimeter.
Use Sturdy and High-Quality Materials
Construct your chicken coop using solid, high-quality materials. Avoid cheap, flimsy chicken coops made of inferior materials, as they are often not predator-proof. A sturdy hen house is a top priority for protection against predators.
Install Hardware Cloth or Welded Wire Mesh
Instead of chicken wire, use hardware cloth (sturdy wire mesh) or welded wire mesh to enclose the coop and run. These materials are more durable and have smaller openings, preventing animals from reaching through and grabbing your chickens. Use them for walls, windows, vents, and doors, attaching them securely to the framing.
Bury the Wire Fencing
To deter burrowing or digging predators, bury the wire fencing or hardware cloth at least one foot (30 cm) underground around the coop's perimeter. Alternatively, create a hardware cloth "skirt" or "apron" that extends outward by at least 12 inches (30 cm) from the coop's perimeter.
Cover the Chicken Run
If your chicken run is open, consider adding a solid roof and/or netting. A roof will keep climbing predators at bay, while netting can prevent birds of prey like hawks, owls, and eagles from entering and attacking your chickens. Ensure there are no gaps between the fencing and the roof to avoid giving access to climbing predators.
Secure the Doors with Latches
Install secure latches on the doors of your chicken coop. Use at least two different types of latches that open in different ways. This way, if a predator manages to open one type of latch, they will be thwarted by the second type, providing an additional layer of protection.
Train Your Chickens with Food Treats
Chickens are food-driven, so you can train them to return to their coop at any time by shaking a bucket of treats. This way, you can ensure they are safe inside the coop when needed, especially at night when predators are more active. Always clean up any leftover food or treats at the end of the day to avoid attracting unwanted predators.

Size and space requirements
When building a chicken coop in Alaska, there are several factors to consider when determining the size and space requirements. Firstly, the number of chickens you plan to keep will dictate the minimum space needed. The chicken house proper should have around five to six square feet of space per chicken if you expect them to lay eggs throughout the year. For context, an 8'x12' coop can comfortably accommodate half a dozen chickens, with 4'x8' dedicated to the laying hens and the remaining space used for storage and broilers.
In addition to the number of chickens, it is crucial to consider the layout and functionality of the coop. This includes designated areas for nesting boxes, roosting bars, and food and water dispensers. The placement of access doors for maintenance and chicken doors for free-range exploration is also important. It is recommended to have a covered run attached to the coop, providing approximately 200 square feet of free-range space for the chickens.
Insulation and ventilation are critical considerations for Alaskan chicken coops. Ensure that the coop is well-insulated to protect the chickens from the harsh winters. One chicken produces as much heat as a 100-watt light bulb, so proper ventilation is essential to control humidity and maintain a comfortable temperature. Controllable vents and digitally monitored humidity levels can help achieve optimal conditions.
The shape and structural integrity of the roof are also important. Alaskan winters can bring heavy snowfall, so a peaked roof design with adequate support can prevent snow load issues and potential collapse. Consider using structural steel and heavy lumber to reinforce the roof and prevent deformation or structural failure.
Lastly, it is essential to provide adequate perching space for the chickens. Square perches are recommended over round perches as they protect the chickens' toes from exposure to the cold, preventing frostbite. Additionally, ensure that the coop has sufficient insulation in the nesting boxes to prevent eggs from freezing in extremely low temperatures.

Roofing
When building a chicken coop in Alaska, the roofing material you choose will play a crucial role in protecting your chickens from the harsh winter weather and cold temperatures. Here are some detailed instructions and considerations for roofing your chicken coop:
Choosing the Right Materials
For chicken coop roofing, it is recommended to use a combination of plywood and a weatherproof material such as metal, plastic, or shingles. Plywood, especially when treated, provides a sturdy base that can withstand moisture and rot. It is important to note that exposed plywood should be avoided as it can rot, mould, and buckle due to moisture exposure.
Metal roofing is a durable and long-lasting option that can withstand harsh weather conditions like hail and windstorms. It is also faster to install compared to shingles. Metal sheeting or corrugated sheets can be used, and metal drip edges can be added for extra protection and a polished look.
Shingles are the most durable weatherproof material and offer excellent protection from the elements and predators. However, they are more expensive and challenging to install. If you prefer the look of shingles, you can layer them over plywood, with tar paper or roofing felt in between to add extra protection from leaks.
Other materials such as marine plywood with roofing felt, PVC, or plastic corrugated sheets can also be considered, depending on your budget and preferences.
Roof Design Considerations
When designing the roof, it is crucial to ensure it has a steep enough angle or pitch to allow rain and snow to slide off. A flat or low-slope roof is not ideal as it can lead to water puddling, leaks, and potential moisture issues inside the coop.
Consider adding eaves to your roof design, as they provide excellent protection from the elements. Eaves are the part of the roof that extends beyond the coop building, typically by 1-2 feet.
Additionally, ensure that you use roofing screws with built-in washers to keep water out and prevent leaks.
Ventilation and Insulation
Proper ventilation and insulation are essential for an Alaskan chicken coop. Include vents to facilitate passive Hi-Lo ventilation, and ensure the insulation is installed correctly, keeping it back from the vents by a few inches. This will help regulate the temperature and prevent humidity buildup during the cold winters.
By following these instructions and considerations, you can build a sturdy and protective roof for your chicken coop, ensuring the comfort and safety of your chickens during Alaska's harsh winters.
