Here in SC it is supposed to drop to 5 degrees tonight... we prepared ahead of time by enclosing the runs in heavy plastic and that seems to suffice for the majority of my poultry, however, my seramas were also given heat lamps, around 9 pm I checked on everyone and the seramas were huddled so I decided to bring all 19 adults & 8 young adults into the house tonight. Set them up in the coolest room of the house in hopes that the temp change will not cause illness once I return them out to their coop tomorrow or the next day. It has been a very windy, cool day - temps began dropping after 3 pm and by 4pm water was freezing over in the outside troughs. Normally we see some winter nights dip into the teens but typically never below 18 degrees (at least not in over 20 years). The serama breeders are in smaller 4 x 6 coops which were covered with plastic and typically the addition of a heat lamp with a 100 watt bulb suffices yet from the signs of discomfort I decided not to risk it tonight. The other poultry (standard chickens, bantam polish, peafowl, turkeys all appear to be fine with just the plastic wind blocks - their coops actually feel warm just from wind control & body heat, the ducks seem to not even notice the cold.
You could say we are a bit protective, but I want to insure comfort of my animals. The sheep & goats all had a heavy grain feeding around 5 and plenty of barn space out of the wind, 14 y.o. potbelly pig had a large warmed meal & heat lamp over her bed, horses grained & then feed warm beet pulp. All of the dogs are inside!
Typically we do not go to the extreme we did over the last few days or feed the warmed beet pulp but as we do not get this type of weather often, we felt the normal measures should be added to. Usually I do not worry overly about winter as we provide good quality feed & hay and protection... but I think you have to also think about what is normal for your animal and as this deep freeze we are all experiencing isn't normal down here, well we spoiled them all a bit today. Better safe than sorry I say.
