So I'm very new to beekeeping. I had a hive set up for me last spring by a teenager who was going to coach me, but he never really got back to. I bought a couple of books & by the time fall came realized I should have been doing more for them than I had! I live in Southern Oregon & right now we're having crazy weather 55-60 degree days & into the teens at night. There's been lots of activity around the face of the hive since the days are sunny & warm. I've been feeding them, but have noticed about 10 dead each day. Yesterday there was no activity & no noise from inside so I took the top off all were dead! There's some yellow gooey stuff in some of the cells. I'm so sad: Any help would be great!
