Feeding these crows is not too difficult, a base diet of quality dog food, adding fruit, pasta, bread, cheese, boiled eggs and cooked meats for variety seems to work well. 

As far as cage size goes the bigger the better.  Indoor and outdoor aviaries can be utilized.  Outdoor aviaries constructed using vinyl coated poultry wire are especially nice.  The black coating on the wire allows you to look at the bird and not the wire.  The wire is also rustproof and gentle on the birds feathers should they choose to land on it.   Remember this is not a parrot and tall skinny parrot cages are not suitable for crows.  Crows and Ravens are the largest of the perching birds and like to hop from perch to perch.  Design your indoor pens with this in mind (longer is better). 

 

Our babies are shipped to their new homes wearing jesses (little straps on there legs so you can snap a leash on).  This allows you to take your bird out for walks without clipping his/her wings.  The leash can be an important training tool.  When a young Crow or Raven grows up wearing jesses they become part of them and are easily accepted by the bird.  Putting jesses on an older corvid can be quite stressful.  In the case of older Ravens it borders on cruelty.  They can peck their legs bloody trying to get them off.  Getting a handfed bird wearing jesses already is a giant step towards having a well adjusted pet.
