Re: Why is One Different?
There may be more bees at the east end due to "drifting". In effect, some bees get confused about which hive they came from, and since the end hives are more distinctive than the ones in the interior of the row, the end ones receive the benefit of the extra bees. One approach to even this out is to move the hives around so the stronger hive is not at the end of the row.
Some people try to make the hives more distinctive with different paint colors or schemes.
Drift is found in the Beesource Glossary:
Note that Barry is seeking additional photos to illustrate many terms in the Glossary. See the messages at the very end of the Glossary for more info.
