I was so excited to get these chicks, I picked them out at Tractor Supply, and was being picky as to the ones I wanted. Had them for 2 days, woke up Monday morning at 6 am to check on them and 7 of the 9 died from being cold. That lamp/bulb was on two weeks old. I was so so mad!!! Heartbroken. I guess if anyone could learn from my misfortune, is with these teeny tiny chicks, place them in a small safe box overnight for added warmth. I don't know if it would have made a difference, or not. Sad thing is, I debated on doing that, but knew the heat lamp is warm. So ******.
