Yes, your Polish is a cockerel...
Yes, as others have said - a necropsy is when you dissect the bird, or preferably, mail the bird off to an institution that does avian necropsies. You can usually find them with a google search in your area - or you can visit this link, which generally has up to date information.

The reason why we recommend a necropsy isn't just for closure, or so we know what happened, but for the safety of the rest of the flock. Avian viruses and disease are all highly contagious to the other birds in the area. Some are treatable, and some aren't. In this case, when you find a bird dead without warning, a necropsy is really the only way to really protect the flock. I previously had turkeys and know they hide their symptoms a bit more than a chicken would.
It is also unlikely that worms would cause sudden death like this. They may have them, but death by worms would be very drawn out.
If you do seek a professional necropsy, make sure to say that it is for backyard poultry. Our local place here has the listed price of necropsy as $150 - but will do one for backyard enthusiasts for $25+ the cost of shipping.
It is also an option for you to necropsy the bird yourself, and post pictures here to the forums. There are a lot of knowledgeable folks who would be able to spot something obvious in the photos. Just make sure to take a lot of them.
