Hello all, I have two pekin ducks and this will be their second winter with us and first in their new pen setup. We have a 10x10x6 kennel with a roof and a 4x4 house attached. There is a heat lamp in the house and we plan on putting tarps around the sides of the pen to keep the wind from blowing through. I was wondering if we should just put two heat lamps in their house (instead of the one currently) to keep it extra warm, instead putting more heat lamps outside. Last winter, we only had one heat lamp in the house and one in the pen. Neither of them seemed to make a big difference. Their water would still sometimes freeze in their house. Also, even if it was freezing outside and their house was warm...they would always sit in the coldest part of their pen. So i don't know how much the cold really bothered them. If it was ever in the teens or below, we would bring them inside, so that's not much of an issue. I'm afraid I will be wasting money putting a heat lamp in their pen because it's such a big area and not well insulated that it won't make any difference. I think having two heat lamps in their house would be best. That way if they were really cold, they could go in their house and keep warm. What do you guys think? Any ideas? Thanks!
