I found seven dead bird eggs in a nest, what happened to them?

Question

I found a bird nest in the middle of some coiled cable wires (Because my father is a carpenter) and some eggs in the front where unnaturally broken. I got a stick and poked deeper into the nest (This is an old nest mind you) and found seven wren eggs all in different places. (Like they where from different broods.) It scared me a little because the entire nest smelled like death so I put the eggs in a little baggy and went inside and washed my hands. I do sometimes find the rare 'dud egg' that failed to hatch in a nest but so many in just one nest is........ unnatural. Any idea what happened?

Answer 1

Where do you live?

It is most likely a predatory bird or a bird such as a crow or rook.

Answer 2

Could be Bird-Flu or some desease killed the whole family and it must have been contagious, dont touchem!
