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

### Instruction:
Milly is making feather boas for her dance team. Each flamingo has 20 tail feathers, and it's only safe to pluck 25% of their tail feathers at one time. If Milly needs to make 12 boas, and each boa has 200 feathers, how many flamingoes does she need to harvest?

### Response:
First find how many feathers Milly can get from one flamingo: 20 tail feathers * 25% = <<20*25*.01=5>>5 feathers
Then find how many feathers she needs total: 12 boas * 200 feathers / boa = <<12*200=2400>>2400 feathers
Then divide the number of feathers she needs by the number of feathers per flamingo to find the number of flamingoes she needs to harvest: 2400 feathers / 5 feathers / flamingo = <<2400/5/1=480>>480 flamingoes
