Ok, last year was my first year beekeeping I started with 5 packages. Just checked all them this past weekend and all 5 are dead outs. I went through the cycle of discouragement and now am ready to re-group and focus on what I can do better this year if anything. I know that this has been an exceptionally hard winter for keepers with high colony loss, I have factored this into my loss. My question to some of you keepers that understand loss and know how to dissect a dead out is this. What signs do I look for when doing an autopsy of my hives to determine what killed them other then an unbearable winter? Things I did do this summer: I started with packages in all brand new equipment, I fed continuously until around the 4th of July, by then the had almost 2 deeps drawn out, from there I put on a super and let them go. I sugar dusted a couple times for mites and left on the honey they saved up from the fall flow. I put some inverted sugar bricks in each hive for a little insurance. A couple of the hives were still alive about 2 weeks ago (right before this last cold snap). All hives still have a considerable amount of stores. I did put a piece of 1" foam insulation on the top of all hives. I did nothing else to wrap them or insulate them. Again what should I be looking for and what will what I see tell me about how they died? Thanks for your thoughts!
