# $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.

$$
Required\ $FEED\ to\ increase\ KG = 25 \* KG^2
$$

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.

$$
Digestion\ time\ in\ minutes = KG \* 60
$$

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
