In Michigan we dont do much for baby birds. I worked at the local DNR Rehabilitation center for a few years and know that they turned thousands of baby birds away. There are fines for possessing wild animals but, in our state its very rare to ever even see a DNR or animal control officer. I would look for local aviaries or nature centers that might take them. Most areas have owl rescue or emergency aviary clinics. If you cant find one get in your car as fast as you can and get to a pet supply and your library!
Libraries should have information about birds in your area. Google has been an invaluable tool for us. She will have to incubate them and determine the stage of the egg. Honestly, if its early on Id just put them back. If youre within a week of hatching timing is crucial and you need to keep them at the right temp ASAP! Im guessing they are cooked or cold at this point. Candle them to make sure. Even if you get them to maturity they may have hatching problems.
Baby bird formula usually comes in a can. I know Pet Supply Plus has a special wildlife formula. Mix it with water and syringe feed the recommended amount. It goes by weight so shell need a scale for food, specially for birds, or well
drugs. The scale we use to weigh the babies was picked up at a local head shop for ten bucks. I know that sounds terrible but it works. Hypothetically if they hatch and she doesnt drowned them when she feeds them (believe me it happens a lot) they could live. But what are the odds? Im not trying to discourage you. I myself have had many a baby bird live on my kitchen counter. But eggs are hard and you dont know how long they have been cold, hot, broken, dead
I dont know if its worth it but Id probably give it a shot.
sorry for the long post, best of luck
