Honestly it's not hard at all the 2 I picked up are from work like you said they are pretty smart so training them is not really a hassle they'll remember you and if you keep feeding them and earning their trust you'll have them perching up on you in no time it took me about 2 months with full grown wild crows (at work mind you) so if you actually dedicate some time it should take less especially if it's a juvenile as for the superstition I got nicknamed brujo which means a male witch in Spanish
