Thank you for your responses. My other four chickens were older when I got them so I didn't have to worry about this. I put the shavings in about a half an hour ago. They hatched on Sun/Mon. They seem to be eating some of the finer pieces, will that be a problem if they eat some? They are picking up the bigger pieces and running around with them like it is a game. It is quite amusing. All of them have gone to the feeders and eaten too so they know where their food is, and everyone is drinking well. With my guinea keets last summer, they said not to put shavings in for the first 2 weeks. When I did put them in, they screamed their heads off because they were scared to even walk. That was amusing also.
