We will be getting our first chicks next weekend and they will be around 4-5 weeks old. We will make a brooder box and use 60w light for a heat source (our house stays 70-74dgs). Do they need grit/sand this early on or just the water and food? Also, I don't think they are handled much so I was wondering if they are still young enough to get them use to my kids and us without alot of stress on them. Any advice is greatly appreciated. We always want our family (including the new chicks) healthy and happy.
