Found some kind of necrosis after harvesting

Looks like congealed blood to me as well. That's not infection.

"Anticoagulant Rodenticide Poisoning in Poultry

Acute pulmonary and peritoneal hemorrhage, after consuming...

Rodenticides can be safely applied to poultry houses so that rodent baits are sequestered from the flock; however, careless application can result in rodent bait consumption by poultry with usually acute toxic effects. First-generation anticoagulant rodenticides, including warfarin, chlorphacinone, diphacinone, and coumtetralyl, require continual ingestion by rodents to induce toxic effects. Second-generation or single-feed anticoagulants, including brodifacoum, bromadialone, difenacoum, and difethialone, can be acutely fatal to rodents.

Clinical signs in poultry are related to the anticoagulant effects and usually observed as sudden death with gross hemorrhagic lesions in one or more body sites, particularly lung, intestine, and peritoneal cavity. These lesions can be confused with flight injury (gamebirds) and trauma from wild animals and dogs. Definitive diagnosis of anticoagulant toxicosis should be based on gross lesions, history of anticoagulant application, and anticoagulant screen on the liver of dead birds (available at several USA veterinary diagnostic laboratories)."

I didn’t see anything abnormal on his insides. And I don’t know of any poison he could have accessed.
