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

### Instruction:
Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan’s bird feeder feed weekly?

### Response:
 Chipukizi anachukua nusu kikombe cha chakula cha ndege kila wiki, hivyo ndege hula vikombe 2 - 1/2 = 1 1/2 vya chakula cha ndege.
Kila kikombe kinawalisha ndege kumi na nne, hivyo chombo cha kulisha ndege cha Ivan kinawalisha ndege 14 * 1 1/2 = 21 kila wiki.
