I had a chicken die outside today and I can only guess it was either sick and didnt show or it got too cold, todays temps are around 29 degrees and its the coldest day we have had this year. I have 17 chickens in a coop that is 8ft x 10ft by 6ft coop with a "heat light" that stays on for 3 hours after dark to prolong daytime and dry the chickens off if they happen to be wet. They have a 10ftx30ft run that is mostly sand as the "floor" because it would rain and get muddy so I use sand. It is fenced in but has no protection from wind, I just always figured they would go inside the coop if they got too cold or something. I feed them 16% layer crumbles only, I have given them scratch as treats but not consistently. They also usually have a flock block in their coop as a treat and a source of extra vitamins. So here is my questions Should I make a wind block on their run? Should I add more to their diets to "warm them"? like crushed corn or more scratch perhaps? Should I run a heat light in their coops all the time?
