I keep a huge tub of this treat mix ready for the guinea fowl. I must admit most people let their guinea be free-range, and get 95 percent of their diet from foraging for bugs and ticks, eating grasses. However, I do keep a station set up with fresh water, extra feed and treats, just in case they want something more. This can be used for the chickens also, because they absolutely have a fit when I am mixing this up for the guineas! I always have to throw them a handful to enjoy, just so I can get past them to give it to the guinea!
Keep in mind these are TREATS … these should not be used as their only source of feed. Also, please remember to provide water for all your free-range animals like the guinea. In heat or cold, even free-range guinea may have difficulty finding water sources that are usually available to them.
