Ohhhh did not think food for roos would need to be different. Im in england and looking to see what I can get for my boys.... They seem to just have layer or treat things like corn feed..... So anyone form England know of what to get roos pls?
I'm not in England, but look for chick starter (unmedicated) or grower feed.
Either one should be safe to feed to all chickens of all ages (need to have a separate dish of oyster shell available for laying hens, too.)
Because all hens start out as little chicks, I assume your feed stores must have SOMETHING suitable to feed to growing chicks. If it's suitable for growing chicks, it is also suitable for mature chickens (exception: certain medications). It's just a matter of figuring out what they call it...
