VERY ODD butchering question

[Newbie_mom]

My sister decided to dispatch a rooster. She said when they went to skin him, she said that the FAT smelled rancid. Any ideas on what could be going on? Should she be worried about her ladies? Last but not least…..Should she still eat the meat?

A fresh, healthy bird should not have a rancid smell to the carcass. Was it her first time processing? Did she perhaps cut into the guts and get some goo on the flesh? If she only smelled the stank when skinning but not after all was said and done then maybe it wasn’t the fat that was smelly but rather just poo or gasses being squeezed out during the skinning process?
