Oh boy , here we go- our 1 week "extreme" florida winter aka coldfront has begun - stayed at 47 in the barn last night and we were trying to heat it up with a chick bulb but i think its to many square foot for too few birds .. it is 56 during the day but tonight it will be 22 degrees , and my floridian birds cant do it. Hubby and I are pulling out the two playpens and cat carriers that house our chickens in the spare room during hurricanes. My "regular" hardy breeds RIR wyandottes etc would prob be ok if left outside in the mini chicken barn that will prob stay around 29 degrees with it being 22 outside , but i know my frizzles and silkies do not appreciate anything below 60 , let alone 40 and below Look out , crazy chicken lover coming through !!!
