Thank you Lynn.
The worker becomes a forager around 21 days old. The first 2 or 3 days are spent cleaning cells, the next 7 to 10 days are spent being nurses to the queen and larvae. Around 14 days old they are busy doing the other duties required to run the hive such as unloading foragers, drying moisture from honey, building and repairing was combs, guard duty and undertaker among other duties.
