You have a horse. Horse manure works much better than chicken manure for my method.The wind chill really is nasty. I think it was -39 while ago. You have a water system for your birds that doesn't freeze but if I left a pop door open all the water cans inside would freeze. I have a heat lamp hanging over the big main water can but it still gets a crust of ice on it. The heat lamp and the heat from 43 birds keeps it around 20 degrees inside the building. Better than what it is outside but still cold. Supposed to be -20 tonight. Think I'll just stay inside today...![]()
