In the coop, full sized Guineas need 4 sq ft of floor space per bird. And they like high perches. Their run size depends on how much free range time they will get, but I would not have it any smaller than the coop size, and it should be covered or they will just fly out. They don't have to be confined to just their coop for 6 weeks like some say they do, but they do need to be confined to whatever their home is going to be for 4-6 weeks so they don't just fly off as soon as they are let out to free range. Just let me know. I have 7 to sell. Just send me a pm if anyone is interested. Thanks.
