How do you look after a blackbirds egg?

To care for a blackbird's egg, it's crucial to avoid handling it unless absolutely necessary, as the parent's scent can deter them from returning. If you find a fallen egg, place it back in the nest if possible. Keep the area quiet and undisturbed, and observe from a distance to ensure the mother returns. If the egg is abandoned or you suspect it won't hatch, contact a local wildlife rehabilitator for guidance.
