I dressed some extra roos this weekend. Some of them had black/dark feathers. In the process of plucking, the feathers broke off the quill, releasing a dark inky looking substance. Is there any way to avoid this? What is the easiest way to remove this stuff after butchering? I have a feeling either my water was too hot or I scalded them too long. I tried to keep the water right at 145 degrees, and I scalded them for 1 - 1 1/4 minutes. Any hotter water or shorter time scalding and the feathers wouldn't come off. Any suggestions? Thanks.
