I am new to this. I have 3 baby RIR. I need to go out of town over the weekend in a few weeks. The chicks will be about 3.5 weeks old by then. We would leave around 4pm Friday and be back about 4/5 pm Sunday. I am not sure if I need to find a chick sitter or if they will be okay for that time. They have a feeder and waterer that are large enough to stay filled for that time. I could clean the brooder right before we left. They are doing really good and this is my first time as a chick momma. I don't want to do anything to harm them. Thoughts/advice?
