I just ordered my first chicks. I have 6 coming of diffrent breeds. So I have been working on getting my brooder ready, I have placed it in the store room in the garage. As we have cats and dont want to take a chance that one of them gets one. I have a large cardboard box and picked up the feed. I have pine shavings in the bottom. What about water? I know some please say to ad ACV to the water to help with boosting their immune system. Any help and info would be great.
