I found a chick on the road (actually my dog did) while walking and I couldn't see a nest so i picked it up and it is now in a box with a towel and heating pad on low. It started opening its mouth so I dont know if it's panting or hungry. I have no idea what kind of bird it is so I dont know what to feed it either. It is black/grey with very long legs. Any help would be greatly appreiciated!
