# $FEED Burning
$FEED exists to keep hungry chikn sate, and feeding chikn $FEED is the outlet for token burning.
Giving your chikn $FEED increases its KG. The amount of $FEED required to increase the size of a chikn by 1 KG scales with the size of the chikn.
$$
Required\ $FEED\ to\ increase\ KG = 25 \* KG^2
$$
$FEED required to increase Chikn KG
The primary purpose of giving your chikn $FEED is to increase the KG of your chikn. But, you’ll need to wait for your chikn to digest after it increases its KG before you can give it more $FEED.
Digestion time increases linearly with level, although players can burn $EGG to skip digestion if they want to level their KG quicker.
$$
Digestion\ time\ in\ minutes = KG \* 60
$$
Digestion time required to increase KG
For example, a chikn moving from 1 to 2 KG would require 60 minutes to digest before being able to level from 2 to 3 KG. If you’re looking to get a nice weight of 69 KG, you’d need to wait 4,080 minutes, or about 2 days and 20 hours, before being able to make the gainz to 70 KG.
$FEED can also be used to skip the GrowingPainz (GP) experienced by Roostr. Just as chikn have a digestion time that restricts their leveling rate, Roostr have a GP timer that triggers whenever they level. To skip the GP cooldown, players can burn $FEED in amounts that increase with KG.
$$
Cost\ in\ $FEED\ to\ skip\ GP\ cooldown = 1000 \* Kg

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.chikn.farm/tokens/feed/feed-burning.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
