We have not had a chance to insulate our coop yet or to close off the extra ventilation from summer and I am a bit worried the coop is too cold/ drafty for the cold weather tonight. I am just wondering if there are signs that adult hens are too cold? They are all on their roosts with their bodies tucked over their toes, but they are not huddled up against each other, they are all a few inches apart. Will adults huddle together on their roosts if they are too cold? Are there other signs that they are too cold that I can look for while they are inactive at night? We have frost warnings for our area and it is supposed to get into the mid to low 30's, but it is not windy at all so will they be OK with all the ventilation open? It is not much warmer inside the coop than out, but it is dry.
