I am considering using sand in my coop as well as in the run. So far I've heard nothing but good reports from people saying they love it! The only one 'bad' thing I read was where one person reported that it was too cold for them to stand in, in the winter. That her chickens preferred to leave the coop and stand outside rather than inside on the sand. Can any of you who live in cold areas comment on whether you've had issues with that? Also, I know that the Deep Bed Method aids in keeping the coop warm in the winter. Not sure sand would help in that. I just want to keep my girls warm. Any comments, suggestions or assurances would be welcome!
