We are supposed to have record temps tonight of 5 f with wind chill -20f the wind is supposed to gust 20-30 mph next 24hrs tommorrows high 16f so im not letting them have as much free range and no swimming. I have my run covered and bedded heavy. I run heat lamps when needed which is not often you no how ducks are lol nothing's ever 100% for sure but I have heat lamps secure. My main concern tonight is their water buckets which are heated ones forgot the exact temp they want work i think its -20f silly question would that apply to windchill temps? My main question if my buckets want freeze should I still allow them access tonight due to spills around bucket and feet possibly freezing and they love to dip would this be dangerous for them in these temps. Love my guys dearly but in my exp I have to be their common sense when it's cold or is it me being to overprotective and they know when their cold? Any advice is appreciated to help my babies and ease one duck moms nerves.
