We had a few extenuating circumstances that lead to a few temp fluxuations, that dropped our live chicks down to 25%, then after storms came through and we lost power for 10 hrs over night, only one of our chicks hatched. We have a desk lamp over our itty biddy temp brooder box and a towel to help keep the heat in, but the temp is hovering right above 90. I'm worried with no buddies our little miracle chick might not be staying warm enough at that temp. He/she seems pretty active and talkative, and seems to be perking up more and more as time passes, but I'm fretting a bit, I confess. Any thoughts on how to keep a lone chick warm?
