My chicks are now 1 week old, growing like weeds, and fighting up a storm. They even have little wing and tail feathers already. But they're eating pine shavings like crazy. I left the paper towels down over the shavings for 3 days, until they were eating really good out of the feeder. But as soon as I took the towels up, they started scratching and eating the shavings. They are eating plenty of starter food, but I worry that the shavings just can't be good for them. So, this morning, I replaced the paper towels. If anyone else has had this problem, what did you do?
