MarsSeed [1] filed a deletion request for chicken-coops [2]: Unused, broken chicken v4 module from 2015. Only a similarly broken module depends 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). PKGBUILD doesn't declare sources, just executes 'chicken install modulename', which is not allowed. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/chicken-coops/
