I’ve come through my first winter unscathed with both of the hives I started last year doing well. Both of them have supers on and the girls are filling them nicely. I plan to start two more hives, from packages in about a week. Can I put the new ones in the yard with my two established hives? Should I be concerned about robbing because of feeding the new hives? Are there any other concerns with putting new packages near established hives?
