I have been looking up information preparing for the winter. This is the first year I will have chickens during the winter and I am curious if what I curious if what I currently feeding them will be sufficient throughout the winter... I have seen it suggested that I feed them cracked corn to assist with producing more body heat... I feed them screenings from our local grainery. The screenings consist of peas (split), cracked corn, sunflowers, flax, wheat, barley, millet, oats and soy beans. My birds LOVE this feed!! Would this feed be sufficient and help with body heat production during the winter months? If you are not aware we have very harsh winters in North Dakota and I want to make sure they are taken care of and getting the right nutrients. I appreciate any and all advice or suggestions! Thanks so much!!
