the brooder box and coop

I set up the brooder box that the chicks will live in until it is warm enough for them to go outside.  I used a cardboard box approximately 2' by 3' with a 1" layer of pine shavings on the bottom.  I positioned the infrared lamp 17" from the ground and I hope it will create the 95 degree temperature that they need for the first week.  I will probably keep it covered to hold in the heat.  The bulb will be raised every week to increase the temperature by 5 degrees until the temperature is about 70 degrees.  Then they should be able to live outside in the coop.  I have attached a picture of the box and of the disassemble coop.  I hope to get the coop assembled this weekend.  The chicks should be here any day now!
