My chicks are 3 weeks old and I have been using wood shavings in their brooder for the last 2 weeks.  I upgraded the brooder to a large box today and at first they didn't know what to think.  Some even acted a little scared.  They all know where their food is and are eating and drinking just fine.  There are a few who have started scratching in the mulch/wood shavings and are eating them.  Will this hurt them?
