Last week we noticed a robin's nest with 3 eggs on our front porch. Days later we saw only 2 eggs. the mother has been extremely attentive. Could she have known one egg was a dud and removed it? Would another bird take it away?
Last year we had a similar nest and suddenly one morning we discovered it completely torn apart and eggs splattered on the porch. We figured it was a snake cause we have seen a snake on the porch and know they can slither vertically up the side of a house.
Any answers? How can we protect the other eggs?

Kudzu we have noticed Grackles or Crows steal eggs all the time, no matter what type of bird it comes from. We caught them in the act.

Why do they do it? What do they do with them?

I'm guessing it is to promote their own kind? or is it just meanness?

Some birds eat the eggs of other birds. Otherwise to diminish the population of the other birds in order to have less competition for food int he future. Of course, they don't sit down and think this out. They're acting on long established instincts.

To answer your question, I might submit an alternate question: From what threat would the parent robins have evolved to instinctively protect the nest?
