Hello, I'm new to the boards and I have a question I'm not sure if anyone can help me with.

I recently rescued a crow fledgling from my backyard and am trying to rehabilitate it. He's got pin on all of his larger wing feathers so can't fly yeet, and most of his tail feathers still have pin as well. He's not injured or seems to be sick (although he's badly infested with mites).

I wanted to ask if anyone might know what he should be eating, if it should be solid, liquid or mixed and how best to feed him?

Also, is it legal to keep him since he's been abandoned by the flock and was in immediate danger of being attacked by another animal?

Any help would be greatly appreciated, thank you all very much!
