Hello new daddy, It depends on what kind of bird you have found whether or not you feed it worms. Not all birds eat worms. Robins are the best known to do so. Little babies usually have a mixture of cornmeal, oats, bread crumbs and some dry cat food for vitamins. Naturally you have to grind all of this up to make a fine mixture. Then put a little water with some and feed the little fella from a small spoon. Be sure that it swallows it down before you give more. I have raised many baby birds in my life time and find that they take a lot of TLC. Usually little birds have to be kept warm and fed every two hours. So you see you have a project ahead of you. First determine what kind of bird it is and take it from there. I hope you have as much fun raising it as I have had in the past. Usually if it survives 48 hours it will survive with your care. Good luck to the new parent. Gremlin Grammie 1976 Green Gremlin
