It's raining right now and is very wet and chilly. I haven't let my chickens out of the coop today to use the run. Should I leave them inside on rainy days so that they don't get wet and muddy? I don't want them to get sick. Or, is it ok to let them out on rainy days. Oh, also.. it's muddy right now too, so I think my white chicken will turn brown and black if I let her out and it's too cold for a bath.
