I'm in NNJ and have 6 RI hybrid hens. It's been getting in the 40s at night and they are starting to slow down egg laying. What are things I need to do to prepare for winter. It gets to as low as l -10F on bad winter. I'm going to have covers installed for the screened openings and will need to figure out water as we don't have electricity back there yet. Also any thoughts on feeding techniques?
