My husbnd just finished building our 8x8 chicken coop and after reading about chickens getting mites, fleas ect. I was wondering if I need to take precautions and dust with diatomaceous earth (DE), or Sevin before I even put chickens in the coop for the first time. We get the baby chicks in 3 days and I know they can't go outside for a month or so. Just want to make sure I am doing all this stuff right the firs time. Thanks, Tammy
