Anybody have any ideas as to how we can keep the shavings out of food and water? They get so full that when we get home from work they can't get food or water. We only have 6 chicks, 4 are 3 1/2 weeks, 2 are 1 1/2 weeks but they are in a smallish brooder (18" x 32"). We a perch mounted diagonally in a corner and a second small branch as well so there isn't much room in there for scratching but man, can they move those shavings around. I am concerned that if I raise the food up too much the smaller 2 won't be able to reach in. Ideas?
