I'm hoping to order 25-50 with the idea of raising them in one of my stalls since it's still going to be cold for awhile. Is 144 sq ft going to be enough for them? If not, how soon do they feather out so I can put them outside in a 12'x16' pen? Do they need as much heat as ordinary chicks or do they generate more body heat and require less artificial heat? My other idea is to use my 20'x20' garden spot -- let them make the organic fertilizer deposits directly. However, that's out in the open and I'm not sure how well it could be heated or closed off from drafts/wind. Any other advice you can offer to make their short lives more comfortable and reduce the risk of loss will be greatly appreciated!
