It is pretty cold and nasty here in upstate NY. The past few days the temps have been in the low 20's and into the teens at night. We have a wicked wind that blows almost 24/7, but they do have a wind block of tarps and straw bales. They are shut in at night, but I have been letting them out in the morning and closing them in around 4:30PM. Does anyone ever keep their girls confined if its gets too cold? If you do at what temps or conditions do you decide to keep them inside?
