Chickenking.sendETHToFee(uint256) (#294-297) sends eth to arbitrary user
Dangerous calls:
- _developmentAddress.transfer(amount.div(2)) (#295)
- _marketingAddress.transfer(amount.div(2)) (#296)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Chickenking.rescueForeignTokens(address,address,uint256) (#304-307) ignores return value by Token(_tokenAddr).transfer(_to,_amount) (#306)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Chickenking.constructor() (#167-181) uses literals with too many digits:

Chickenking.slitherConstructorConstantVariables() (#127-401) uses literals with too many digits:
