See options on AmazonThe instinct in November is to seal the coop up tight. Poultry specialists at the University of Arkansas Cooperative Extension say that is the mistake to avoid: a coop still needs air exchange in the coldest weather, because moving air carries out the moisture and ammonia that build up overnight. Damp air is what turns a cold night into frostbite.
1. Vent high, block low
Keep roof vents open, or leave a window partly open and cover it with burlap to hold some heat while air still moves. Then walk the coop and fix drafts at bird level: gaps near the floor and roosts are the ones that matter.
2. Wood roosts, off the floor
Give birds a roost so they are not sleeping on a cold floor. Use wood. The extension team specifically warns against metal and plastic roosts, which hold cold and can contribute to frostbite on feet.
3. Deep bedding
Four to eight inches of wood shavings on the floor adds insulation. Insulating the walls is worth considering in colder zones.
4. Heat only if you need it, and do it safely
The extension guidance treats supplemental heat as something for temperatures below 35°F. If you add heat, a radiant option such as a brooder plate or an approved heater is the safer route; if you use a heat lamp, follow every fire warning on it. Place the heat at about nest-box height or the lowest roost rung, and use a thermostat or thermometer so you know what the coop is actually doing.
5. Water that does not freeze
Continuous access to clean, unfrozen water is the single most important winter job. A heated waterer or heated base saves the twice-a-day ice chop.
6. More feed than you think
Birds may eat up to 25 percent more feed in cold weather, so keep extra on hand and keep feeders topped off.
7. Watch for frostbite and cold stress
Frostbite shows on combs, wattles, toes and feet as blackened or gray tissue that feels brittle; call a veterinarian if you see it. Fluffed feathers and tight huddling are signs of cold stress.
8. Gather eggs often
Collect eggs regularly so they do not freeze, and throw out any that are cracked or frozen.
