MarsSeed [1] filed a deletion request for chicken-check-errors [2]: Unused, broken chicken v4 module from 2015. Only some other similarly broken modules depend on it from same year. Repo's chicken and AUR's chicken-git are at v5 and incompatible with these leftovers. Also upstream URL is gone (unreachable).
