We found a pigeon yesterday in my backyard, my dog was playing around with it and we noticed it and that she might have injured it. It won't fly at all but does run and walk fine. It won't eat or drink water. I have it in a nice contained space were it can feel safe and calm.we check in it every 30 minutes but is the same. We tried letting it be outside alone and see if it was fine and just fly away but it just ended up coming back to the door walking. What do we do, we need help we are not experienced with pigeons.
