to introduce my chicks to the pine shavings? I currently have them on paper towels covering up the shavings below. They are now about five days old. I put them on shavings a little while today, but they would dig through it and pick through the smaller shavings. Is this what they should do, or is this a sign that they'd eat the shavings all day long? I want to keep the number of chicken backsides I have to wash at a minimum! (wishful thinking, I know ) Thanks!
