Now that it's winter here in Washington state my Golden lace wyandotte stays in the run or coop; normally summer time she free ranges half the day. We have Cold temps right now. I was wondering if I should set up some kind of dirt bath in the run for her. I would tarp off part of the runs sides so rain or snow don't blow in. Maybe use Sand? Or mulch? Do they even need the bath in winter? Plus I have 3 10 week olds, do they need to have a dirt bath yet? Any information would be so helpful and appreciated. Thank you!
