Brood 4: Brood Area
The Brood Area for each of 4 colonies (each a different scenario) was measured over the 2018 season during the weekly inspections. A Perspex template was used on which a grid was drawn with squares of 5 cm side. Holding this over the brood frame enabled the area of brood to be calculated by counting the number of squares covered and multiplying by 25. Measurements were taken until the middle of September.
Hive 12 This proved to be the best colony over the season. The brood area would have been larger if the colony had not provided 4 frames of brood for nucs and acted as the colony for the Ben Harden method of producing new queen cells.
Hive 01 was progressing very well until it swarmed on 03 June. At the time I was getting into my bee suit to do the weekly examination; only this time I was two days too late after some poor weather.
A new queen developed from a swarm cell and the colony built up again during the summer.
Hive 09 never really recovered from the extreme weather in March and April; or was she just a poor queen. The brood area was always way behind what would normally be expected.
A queen cell from a mother queen was inserted after the old queen was removed at the end of July. A larger brood area might have been expected from the new queen.
Hive 04 In this case a newly mated queen was introduced to a nuc 12 June. The frames were transferred to a brood box 24 June and the small colony allowed to build up over the summer.
