By cook, I mean provide heat. I don't know why the idea scares me to death, but it does. I may be getting 19 guinea keets on Friday, they will be 7 days then. Our house isn't a/c and the upstairs stays pretty warm. How crucial is it that they stay at 95 degrees (is that right?), and for how long? Also, how much space will I need? Obviously they will grow, so how much room for my week olds and how much by the time they can go outside? Thanks!
