So it's supposed to get down to about 33° F a couple of nights this weekend.
I'm not worried about my BO's, but how well will my Silkies hold up?
Should I put a heat lamp in the coop, or plastic on part of the run to give them somewhere to take refuge?
This will be my first winter with the flock.
So long as they can get under cover and the coop is relatively draught free , they will be fine. Heat lamps can be very dangerous and won't help them to become ' cold hardy '.
