All my hives are from swarms I've captured here in the Texas Panhandle. At this time of year we have big temperature swings and I've noticed a big difference in the hives as far as when they begin flying. I have a couple of hive that were flying today when the temps were still in the mid 40's but most don't come out until temps reach the mid 50's. Has anyone noticed this type of variability in their hives? Are some hives more cold hardy? Would you consider this a good trait (finding the earliest spring pollen) or a bad trait (burning up stores before anything is out)?
