I start with shavings. If the chicks are only a day or 2 old, I put paper towels over part of it and sprinkle their food there so they can find it easily. After a day or 2 the paper towels come out & the chick feeder goes in. I've not had any problems this way.
I start with a layer of paper towels and about a week or slightly less I switch to shavings. They know where their food is by a week. They will "try" the shavings at first but like I said, they know where the food is by now. Good luck and we would love to see pics.
