I was giving water and food to our chicks just a few minutes ago in their brooder and they totally freaked out!!! They all ran to the far edge of the box (which is not very far at all) and they were like going crazy, like I had sent a hawk down to eat them or something. I don't know why they did this, they are 10 days old. We handle them as much as possible, but they still seem so scared of us. What are we doing wrong???
