### Instruction:
 Bwana Curtis ana kuku 325 kwenye shamba lake ambapo 28 ni jogoo na wengine ni kuku. Kuku 20 hawatowi mayai wakati kuku wengine wanatowa. Kuna kuku wangapi wanaotowa mayai kwenye shamba la Bwana Curtis?


### Response:
 Bwana Curtis ana kuku 325 - 28 = <<325-28=297>>297.
Kati ya kuku 297, kuku 297 - 20 = <<297-20=277>>277 tu ndio wanatowa mayai.
Hivyo, Bwana Curtis ana kuku 277 wanaotowa mayai kwenye shamba lake.
