I believe that they are sparrows (there are three of them) that were blown out of their nest during a storm last night. They have gotten their “big feathers” but are still naked under the wings and have bits of down poking up. I have them together in a cage in shredded white paper. The pet store said to use wild bird formula, but until I get some of that, to use powdered Cheerios cereal mixed with enough tepid water to make a gruel and feed them with an eye dropper. They seem to be taking to this ok, but I’m concerned that I’m not giving them enough or maybe even too much. Any ideas until I can get the formula?
