Along the same lines, how far apart do you space you bee yards? I realize that there are different characteristics such as available forage, climate, number of hive per yard, ect. But, can you generalize how far apart you would have to place yards containing 40 hives with average forage? 1 mile? 2 miles? Ect.
I have 4 hives at one location and would like to expand it to, say 40 hives. About 1.5 miles away, another farmer said that he would not mind if I put some hives there. Is this reasonable if some day in the future I had 40 hives at both locations?
Finally, how do you know if the density of your hives is to great? Do you look at per hive production or something else?
