I helped a friend with her top bar hive today.
Apparently the hive was healthy and high in population when she looked in a few weeks ago (though she never went through the hive all the way to the front). Today what I saw was low population, scattered brood pattern and somewhat sunken caps. Many open caps had the remnants of the brood in--looking a bit like chalk brood--dried up and white. When I scrached the surface of the capped brood there was either white goo or next to nothing (dried up) inside. I did not try stringing the goo, as I have never encountered AFB and so did not know to do that. But also, there was not a noticeable foul smell (I have smelled the EFB before and that really smells bad). So I wonder if this sounds like any other brood diseases you have heard of?
Any thoughts appreciated--
