[@Blackmist16] you will have room 9

[@xXSINXx] Where will your crow sleep? Can it sleep in a fake tree? Perhaps in a hole of a fake tree? I encourage creativity and imagination when making new creatures.  You will be hatching this bird out of an egg so go look at a couple Avian ones that are already made up.

Overall, it looks good. I just think that you will need a leg band perhaps a leash while young. Other toys can enhance your pet's intelligence. Also check out the shadowcat. There might be other ideas to be inspired by you.
