Do I need to keep my chickens warm in the winter?

There is no need to take action to keep your chickens warm in the winter, as unlike us, their body temperature is 105 degrees and they also wear a feather duvet jacket!  Ensure that your hens have adequate ventilation to avoid the build-up of ammonia and condensation, and that your run is weatherproof in winter to keep the ground dry.  Consider covering the run in winter to keep dry, and provide shade in the summer months.
