IMO, if you have a safe, secure grow out pen or coop/ covered run situation ready for them they can go out now, but I would still provide them with a light for heat. It's common practice to start keets out at 95 degrees the day they hatch then reduce the brooder temp 5 degrees with each week of age as they grow (measured on the brooder floor, in the center of the glow from the light) until brooder temp is close to outdoor night time temps or they are 6 weeks old and closer to being fully feathered and can regulate their own body temps better. Right now your keets still need around 80 degrees of warmth...
