I believe that we each have to do what we feel is right for our situation. We each have our own reasons and our own situations as to why and how we raise our guineas, or any of our other animals and I really don't think any of us should be judged as "not caring" because we choose a different way.
Some of us have our guineas not only because we love them but because we need them to help maintain our property to keep ticks away. I live on 5 acres of mostly woods and ticks are a very big problem. While it would be nice if I could keep my wonderful guineas safe in a big run, that would pretty much defeat what I really need them for. It would be wonderful if I had a big coop to keep them in, but right now that is not possible, so they roost in a dog kennel. Safer then the trees but not completely predator proof by any means.
Some people choose to take their guineas eggs and incubate them, some choose to let their hen hatch her own young. Some raise their keets in a big box under a light, some choose to let the hen raise her keets. Some keep their guineas locked up, some let them free range. Some let their guineas roost in trees, others have barns, sheds, or coops for their flock. Some use their guineas to make money, some use their guineas to help with pest control. Everybody's situations and circumstances are not the same and we each have to figure out what works for us, without being judged for those choices.
