Don't have any advice for you on the bird but we did have to foster 6 baby ducks for a while and keep them in the house at night. The dogs really sniffed the cage and wanted to get at them. During the day they were outside in a larger cage. The dogs were told to leave them alone and did. I am sure if they got a hold of one they would kill it but not because they were being mean, they would want to play with it. They have caught wild birds in our yard several times and they always end up dead. As long as you let the dog know not to mess with it and keep inforcing that you shouldn't have any trouble. Most of the time boxers just like to play and don't realize how strong they are.
