Pigeon help

[BanqMac5]

There were a few girls that had found a pigeon (which couldn't fly) that was in a common area and they had given it to one of the biology teachers. I happened to have come across the bird and decided to take it in thinking it would be easy to take care of since I have 5 budiges and 2 love birds. Now that I have the bird home, from what I have observed and researched is that the bird is still a fledgling and doesn't know how to fly. My question is what should I do with her/him now? I give it food and plenty of water but I'm not sure it eats much. Is it at that stage where it eats seeds etc.? Or should I be giving it bird formula?
