I really have read the forums but still confused. Getting 4 pullets (not sure of age - mixed breed) from my husband's co-worker in just a couple days. The owner says he feeds his chickens "scratch or corn chops". I done even really know what that is! Yes, I know nothing. Unlike his set up which is mostly free range, they'll be staying in a coop and run here. So, please tell me what to feed and any supplements I need. Also, are there any medications I should be aware of, like wormers, etc? I'm excited, but getting nervous realizing I know nothing.
