I’ve read so many articles about not allowing the temperature inside the coop to dip below 40 for Seramas. But, I’ve also read that other “Northern” Serama owners claim theirs can tolerate well below 40. I’m one to worry TOO MUCH about my tiniest chickens, so I manage to keep them fairly comfortable above 40+ inside their insulated building. On extreme bouts of cold, if I’m unable to retain an inside temperature of 40, I run temporary heat by the use of a wall unit with an automatic shutoff once it reaches the right temperature inside the building. I must admit that I take a few extra measures to ensure that my tiniest chickens stay winter-safe.How low can they winter temps go before they need heat supplementation?
