1. Provide a warm, draft-free shelter. Pigeons are susceptible to cold weather, so it's important to provide them with a warm place to roost. The shelter should be well-insulated and protected from drafts.
2. Keep the pigeons dry. Pigeons don't like to get wet, so it's important to keep their shelter dry. This means making sure that the roof doesn't leak and that there's no standing water inside the shelter.
3. Provide plenty of food and water. Pigeons need to eat and drink more in the winter to stay warm. Make sure they have access to plenty of fresh food and water at all times.
4. Give them a place to dust bathe. Pigeons need to dust bathe to keep their feathers in good condition. Provide them with a shallow pan of dust or sand that they can use for this purpose.
5. Monitor the pigeons for signs of illness. Pigeons are susceptible to a variety of diseases, so it's important to monitor them for signs of illness. If you notice any problems, such as sneezing, coughing, or lethargy, take the pigeon to a vet right away.
