Staking your $egg token generates $feed token, currently 3 $feed for every egg staked per day. Deposit enough of this $feed token into your chikn, and then you can grow your chikn kg. Feed is claimable at any time, with no lock periods or minimums. Unstaking your eggs will incur a breakage fee of one in every twelve eggs, or 8.33%. The feed cost to grow a chikn increases by a square factor per kg, feed = 25*kg^2.
