i went thru my deadouts today. 2 of the hives had a couple frames with dead sealed brood. when i scraped the cap off and dug out the dead larva on a couple, it was black and mushy almost liquid,but not stringy. caps didn't appear sunken. didn't have my camera, may go back in a day or 2 and take a few pics. kinda worried now, would hate to have to burn all my equipment and my hive that is robbing them out. any opinions? i know i can send samples to be checked, just checking to see if anyone has an explanation.
