there are two birds in the process of this: the house finch and the brown-headed cowbird. the house finch is the one that built the nest and laid the blue eggs. however, that speckled egg was laid by the cowbird. the cowbird does this to use finches to raise their own children, not really regarding the harm caused to the baby finches.
A robin, lays tiny blue eggs, often a color that may be called turquoise, but color is an opinion of the individual viewing it. However robins lay their nests on ledges of sorts, not in trees, so if you saw the eggs in a nest on that sort of surrounding you can be pretty sure it's from a robin. If in a tree, it would be something else.
