For our first year of beekeeping last year we got two hives. One of them did great, the other died off at the end of the summer. We put a new package of bees in this hive this spring, but the brood boxes were kind of weird. Especially the top one which we haven't put back on yet.

Here are a few pictures of the brood box, complete with dead bees from last year. Do these look normal? Did this hive likely die to do not getting enough food, or drifting or robbing from the other hive next to it? I wanted to make sure it wasn't due to disease. Also, why does the comb looks so uneven?

Thanks!
