There is very little chance for this. In order for an owl to be tame, it is necessary to grow it, but then it will not be adapted to life in the wild and may die. To grow an owl, you need to understand that owls are predators. They need to be fed with mice or chickens, because they need the skin with wool for digestion. Are you ready for this? I buy frozen mice and frozen day-old chicks. I can't feed them live mice or chickens... Then it must be adapted to live in nature. This is a complex process. There are few chances that it will then fly to you. This option can work with crows.
