I set 45 eggs on 2/12/08 at noon. I am going to remove the turner on 2/29/08 at 2pm. Is that too soon? This is a classroom project, and the room will be locked on 3/1/08. I am trying to make a brooder for the 38/45 fertile eggs. I have a big card board box and a 250watt red bulb. What should I line the box with? Any other advice for the hatching stage?
