I have never used this method to feed my bees so I had a few questions about it
1. Can open feeding start a robbing feeding or can it help stop one?
2. How much syrup do you put out at one time and how often do you refil your barrels (currently I have about 150 hives in some locations and I was thinking of using 55 gal barrels to feed out of)?
3. What are some other pro and cons on open feeding?
