I believe I saw you on the corvid list recently ??? - I replied to you there.
If not, this is as valid here, as anywhere. Ok - No more arguing wiether the bird is legal or not - Im pretty sure, now, after doing some more reserch, and asking around, that American Crows are legal to keep in Canada, (check your local F&G ordinances)and carrion crows are, I believe, legal in Europe, but I know that native corvids are entierly illegal as pets here and anywhere in the USA -
No exceptions -
I would say if your local "pound" has crows that need homes, I would aquire one for company for your bird, to put with him in an outdoor flight (I will detail later) - Corvids do best in the company of others of thier species.
Your diet sounds pretty decent, but I would add things like fresh fruits like a good quality soaked parrot pellet (formulated for macaws is nice), some dry dogfood, like "benifuill", grapes, cherries, and chopped apples, and meats like pinkie, fuzzy, and small adult mice, and fresh sliced lean beef, beef heart, venison, etc.
On an extremely important note ! - In my photos you will see several of my trained pet birds have chords on thier feet. These are called Jesses.
TO ANYONE WHO HAS A CORVID - I would most deffently not jess your bird! Especially if he/she is just "easier to handle" because of the jesses. That probably means he was staying on you out of fear of being strapped to you, rather then because he wanted to be with you. JESSES ARE FOR RAPTORS, AND TRAINED RAPTOR HANDLERS.
I use jesses on many of my tame pet birds, but I am a trained bird handeler, and my birds are all extensively trained. Jesses are not to keep birds still, or "hold on to them" - They are a teaching aid to let the bird know when to fly and when to sit tight. If used inproperly even on tough birds like hawks, you risk severe injury to the birds.
Your birds temperment changes are likely from fear and shock wearing off, rather then a new fear of you. A birds calmness during new situations can often be mistaken for "tameness". Once a bird settles into its surroundings, it will often act much much differently then when I has first arrived. This goes for any birds, and for that matter, most animals.
If a pet bird on jesses bates (attempts to fly away), especially out of fear, those jesses could break one or both of his legs, or his hips.
For your crow, I would not jess him at all, and for any reason. Im sure, in addition to the possabilaty of breaking his legs or hip, subject him to severe arthitis during his lifetime - Without the abilaty to fly, your crow will already be on his feet, and useing his feet harder, and for more then a normal flighted crow would.
Try to train him with food reward (pinkie, and fuzzy mice in my experiance work well - I haven't found much else that they cant "do without"
to come to your hand, and take food from your hands. Then you can work on trying to train him. Just being around him may help some.
Being a wild animal, he may not come around once he gets comfortable with his situation. He could even become aggresive if kept inproperly, and afraid of you. I would not suggest you force him to by useing jesses, or by holding him tightly, and would suggest that you rather just provide for him and build him a proper flight. Im sure he will not, for the long term, be comfortable, or tame if kept in a "bird cage".
He would probably enjoy a walk in flight, even if its built low -It would most simlate the outdoors and wilds he is used to. It would probably help you to "tame him" too, being able to get close to him, and interact with him, in an eviroment where he will eventually feel safe.
I would suggest you build a 9 foot, by 6 foot, by 5 foot outdoor (can be longer, or wider, but I would not make it higher) (or indoor if you would prefer, and have the room and time to maintain it) flight for him, (and a friend if you can aquire one legally )with lots of different perches for him to choose from.
You can even incorporate a partiual tree or large limbs in it for him to get around on. Sawed stumps, or "slices" of dead trees can make nice perches for birds with damaged wings. - Shelves biult in to one of the walls of the flight work too - you can make a "stair effect" (like "illistrated" below), by positioning them, so he can get up high, where he will feel safer.
Single boards
Nailed in
make stairs
The flight will need a sheltered are for the birds to keep out of the rain, and such, but a quality flight can probably be well constructed for around 250$
If he calms down, and AFTER he is calm being handled, I would like I suggest to all bird keepers, purchase a feather teather harness. - It is a much much safer option then jesses. It is built as a leash to hold onto a bird with, ulike what jesses are desighned for.
