Just picked up my 2 feeder pigs today. They look good & healthy, Well we had a cold snap. I tried to delay getting the pigs till next week. But it didnt work. Its supposed to get down to 8 degrees tonight. Ive got them in a 12X22 pen with a 4X8 house with a bale of straw on the floor. I wasnt planning on putting a light on them, but Im wondering if I should put one on them till morning.. What do ya think.
