I inspected my hives yesterday and one of the weaker ones had noticeable mites in some of the drone brood where it pulled apart at the bottom of a frame. I am now noticing a couple of bees here and there walking on the ground in front of the hive with either one or two of their wings deformed. There are not a lot of them just a couple here and there. When is too many too many? Is a hive doomed at this point or is there still hope. I have come to terms that I will have to let this hive go to see if it survives.
