Saving a Robin's Egg

On my way into my office today I found a lone Robin's Egg in the driveway. I wasn't sure what to do, so I picked it up and took it inside. Figuring that the mother would have a heck of a time getting it back into the nest herself.

I consulted with Robin - who works for the chiropractors downstairs hoping that because it was her namesake she would know what to do. Evidently, I wasn't supposed to have touched it , although, it's fate was pretty much sealed being so far from the nest in the first place.

I've made a nest and put it on the front porch as it does tend to be the warmest place in the building, sunny too.

I'll try to post a picture and hopefully, the poor thing will be okay, although the outlook is not too good.

I tried - Do you know how to save a robin's egg?
