Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
A small poultry farm has 300 chickens, 200 turkeys and 80 guinea fowls. A strange, incurable disease hit the farm and every day the farmer lost 20 chickens, 8 turkeys and 5 guinea fowls. After a week, how many birds will be left in the poultry?

### Response:
 Kuna ndege 300+200+80 = <<300+200+80=580>>580 jumla
Kila siku ndege 20+8+5 = <<20+8+5=33>>33 hupotea
Baada ya wiki ambayo ni siku 7, ndege 33*7 = <<33*7=231>>231 zitapotea
Kutakuwa na ndege 580-231 = <<580-231=349>>349 zilizobaki kwenye shamba
