I am in my first year (2months) of beekeeping; the hive is doing well with two brood chambers and a very active queen. I am thinking of adding a third brood chamber in the hopes of splitting next spring and adding honey supers on top of that.

When should I use a queen excluder? I recently read a piece in one of the catalogs suggesting that a queen excluder is optional equipment, my plans don't include a large honey harvest. Do I need one? Also can these be made or do they have to be purchased.

Thanks for in advance for any help or suggestions.
