How do I keep Kadaknath chicks alive in the first weeks?

Early chick losses in any poultry, including Kadaknath, come mostly from poor brooding, chilling, dirty conditions and disease. Get the basics right: a clean, dry, draft-free brooder with proper warmth (chicks need steady heat the first weeks and you reduce it gradually), clean water with the right feed (good starter feed), enough space so they do not pile, and strict cleanliness. Start chicks from a reliable hatchery so they are healthy to begin with. Kadaknath chicks are a bit slower and delicate early, so warmth and hygiene matter even more. Vaccination and any medication must follow a veterinarian's schedule for your area, do not self-medicate, since the right vaccines (for diseases like Ranikhet or Newcastle and others) and timing should be set by a vet. For sick birds, consult your local veterinary doctor promptly.
