I used to have guineas and they were very hardy birds as adults but I learned the keets need a bit of looking after until they at least are feathered out. Yours are still babies, they wouldn't be able to fend for themselves yet. If it's warm enough and your wanting to let them get used to outside, fix them up with a small fenced in space with a cover so they can't jump out and nothing else can jump in. I used an old playpen turned upside down so they were on the grass to scratch about but they were protected and it was easy to move it to a clean spot every day. I gradually moved them onto the fenced in chicken yard so they could start getting used to the rest of the flock and vice versa. Eventually I cut a hole in it and they were able to go out with the big birds but could hide back under the pen if they needed to. When they started roosting in the coop with everyone else I took out the pen. They did fine at that point, when they got full grown they started flying right over the fence and were happy being wild. Guineas are funny creatures, they're very loud(we don't have neighbors so that wasn't a problem here) and they can be territorial. Mine got to where they chased and sometimes attacked anything they felt was intruding- snakes, possums, wild birds, even cars and tractors. Unfortunately it was them chasing cars that did them in. They're lots of fun though so best of luck with them! Maybe someone else can give you some more ideas and you'll be able to find what works best for your situation!
