This morning we went to a chicken sale as a seller and ended up as being mostly buyers, just like every time. We got 5 guinea keets, and we've never owned guineas before. Any clues on how to care for them? Should we feed them chick starter or chick starter/grower? I don't know how old they are. They're feathery, that's all I can tell. How long do we have to keep them penned up? I've heard you have to keep them caged for a long time to get them to come back every day. How long is that? Six weeks? Six months? Thanks!
