To incubate a blackbird's egg, you need to maintain a stable temperature of around 37.5°C (99.5°F) and provide humidity levels between 40-50% for the first 18 days, then increase humidity to 60-70% for the last few days before hatching. It's important to turn the egg gently several times a day to ensure even heat distribution and prevent the embryo from sticking to the shell. If you're using an incubator, make sure it can regulate temperature and humidity effectively. Always handle the egg with care to avoid damaging it.
