I was just informed today that my 9 chicks are coming next wednesdsay. Panic has begun. Is there a sq ft recomendation for the brooder. I have 3 chicks 3 wks old and 9 new chicks coming next week. The box is 18 x 26 and 2ft tall. Also, is there some where I can see a list of terms. I keep seeing things like DH and EE and DE. What does it all mean? Thanks Sarah The smelt are running!!
