Hello, I'm a novice hobby beekeeper..I have an observation hive on a second floor. It seems the air pressure of outside is much stronger than indoor. Thus, there is a strong rush of air into the opening of the beehive..The bees don't seem to appreciate the constant cold air..i can't not open the window to equilibriate the air pressure..Does anyone have any suggestions and recommendation of how I should correct this problem..Thank you in advance.
