hi i'm right next to you and I don't use heat I sometimes put a TJ. Blanket on t op if there coop and extra hay in their nesting boxes.Hi, I'm new here and wanted to introduce myself to other San Diegan Chicken-keepers. We have 3 hens in the Normal Heights. They are a Buff Orpington and 2 Barred Rocks - we raised them from chicks and they are about 7 months old now (and started laying at 5 months!) I have a question, this will be our girls' first winter, do you heat your coop in the city, or are they ok in there at night? Thanks in advance for the advice!
