Guineas need a dry environment with plenty of room. Since most people raise guineas with the intention of letting them run loose after reaching adulthood, space is usually not a problem. If you are confining your birds for any length of time, give them as much room as possible outside and a minimum of 2-3 square feet per bird inside. The more room they have, the less likely they will become overly stressed. Guineas tolerate weather extremes well after they are fully feathered and have reached adult size.
Guineas begin to fly at a very early age and can be confined only in covered pens.
It is not unusual to find adults 20-30 feet above the ground complaining about everything they see. The laying season will vary depending on your latitude and local weather patterns. The Pearl and Purple usually have the longest laying season and the lighter colors have the shortest. The guineas' natural diet consists of a high protein mix of seeds and insects. If your birds have a large area to roam they will usually get enough to eat on their own, but you can train the birds to stay closer to home by providing supplemental food in a regular location.
