This was a comment but was getting too long:
god that is a big area with a lot of unknowns. If it was me i would use another programe (AutoCAD) to create an array of circles with an area of 2000sqm each. then over lap them (or not but will be a lot of holes between each circle if not). then pick out the centre points of each and make sure your array is bigger than the area you need.....assuming the 600 ha is not just a square.
import dxf to QGIS. Overlay the area (600ha) onto this. create a shape file of the array by eiter spliting the layer or saving as shape. clip the layer to that of the area....and i think that is it.
So the image below is a very zoomed in area. Based on the statement that the bees cover a 0.2Ha area the area of the circle are all 2000sqm. bees do fly in straight lines but not squares. interestingly i creared 4 different dxfs 2 for hives and two for areas covered. and just worked of these without splitting.
the centre point would be a hive. so you are looking in the range of (55x55)x2....a lot of bees if it is a square 600ha.
