So im in WI and we had a rather long winter this year. I wasn't able to get any feed into the hive until recently and noticed that a large majority of the hive was dead and weak, but still around and active. I now look and I only have about 10 bees and the queen which are all in the top super (I have 2 brood boxes and 2 supers) ive looked up some things and wondering if it might be CCD but I don't want to tear the hive apart to investigate in depth for fear of loosing the queen. Is it worth trying to salvage this hive? could I introduce a new bee colony to the existing loyal contingent and their queen? This is only my second year so not to experienced yet, any and all advise is greatly appreciated. Thank you in advance.
