Good luck man. Im at the same endeavor as you right now but a slight bit ahead of you. Some people have had success keeping them with chicken i am trying to do so, tho the guineas can be a lil agressive towards them its working. I put nesting boxes on the ground to try and get the chickens to encourage them to use the nesting boxes too but the guineas still get flighty and run or fly across the nesting boxes and will poop on eggs ocassionally or break. Its the one down side. Guineas are ground nesters so that was my thought tho i think am going to hang the nesting boxes higher again and just make sume sort of corner with tall field grasses around it instead for them. tho i am sure sum of my guineas did. Use the nesting boxes there was still spoartic eggs randomly on the floor and a hayed and wood chipped enclosure. Just sum info on ny set up fpr your. Knowing sum of what to expect and these ares young guineas like not a gull year yet bossing around my year and cpuple month old chickens. They specifically pick on one for sum reason lately it seems. He has less tail featjers than the rest and if you dont have a raccoon trap get one and bait it often.
