The Edgerton Post Office is a small local post office that doesn't handle packages passing through. Its very likely your package is at the Annex facility out by the Intermodal. I would suggest talking to your local office and asking them to send an email to the sorting facility or filing a report on the USPS.com website.
The Edgerton facility is not the same as the Edgerton post office. You'll need to go through your local PO.
