Thanks, HennysMom for the quick reply. I think I should have explained a little bit more, though. I'm trying to find out about a mineral supplement called Poultry Spice used in the UK during winter/moulting. I can't seem to find out whether it or something like it is available in the U.S.
Does anyone know of a source for "Poultry Spice" (or a comparable supplement) in the U.S. ? Or can someone in the UK provide a list of ingredients?
Many thanks
