Newbee here. Got two 3lb. packages on Saturday and installed them without a hitch into 2 new hives at my dads which is an hour away from me. My dad had bees for about 10 years but hasn't had them in the last 15 yrs. Anyway on Sunday he called me and said 1 of the packages had left the hive and was on a tree about 5 ft from it. He put them back in and told me they might do the same thing again because we installed on all new equipment so it didn't have that "bee" smell on anything. Well he called last night and said they were gone and he looked all over and couldn't find them. Needless to say this hasn't made me too happy. He told me the other hive looks like everything is going good. He said bees are bringing back pollen so that means the queen is out and laying eggs. He also said he thinks he should of taken the frame that has the eggs started on it and put it into the other hive that flew away and that might of kept them there. Oh well, live and learn.
