This is my first year with my guinea hens. I posted on here already about a heat lamp in my coop for the chickens, which I was told I don't need one but then someone said to double check for the guineas. Do I need a heat lamp for my guineas? I live right on the southern shores of Lake Ontario in NY, winters is usually around 20-30 degrees with nights into the teens. It always seems to be that we get a few days or weeks of below zero during the days. For snow we get over 10 feet with a wind of some sort. I want to keep my guineas and chickens happy and healthy this winter. Thank you for your help!
