Ok.. I am wondering if I am making a huge mistake here. I received an order from Ideal last week of 11 chicks. 7 are bantam and 4 were EEs. I have 5 chicks already in the brooder that are about 3 week solder, 3 RIRs and 3 bantams.. I got the chicks home, made sure they were all drinking and eating.. and the next day integrated them with the older chicks in my indoor brooder. Smooth as glass.. One EE chick passed away a day later.. On Monday or so I moved the entire lot to the coop in this set up I lost another EE on Tuesday, found her dead in the wood shavings... We lost power Tuesday and I added lots of hand warmers to the box.. the rest of the chicks seemed ok.. Went out today and in the small box found another chick.. flat as a pancake..dead Are they too cold and smothering one another??? The coop is fully insulated with R11 insulation. The door to the run is closed and latched shut at night.. the heat lamp stays on at all times..
