I know this has been gone over ad nauseum, and I have searched past posts, but I just want to check. I bought some Purina Flockraiser for my swans (born 5/3/08), I thought it wasn't medicated, but it IS! With amprolium. Can I feed this to them? Or just go find something else and give the flockraiser to the guineas & turkeys. Any other suggestions besides layer pellets.
