Hi All, I have eight 1-week old chicks (4 BO, 4BR) who will be of egglaying age sometime in December or January. I'm in the Northern US, so it will be in the coldest part of winter that this will happen. I have no plans to light the coop artificially. Should I even expect eggs this winter? Even if there are no eggs, would it be wise to mix in a small amount of layer feed anyway to provide calcium as a nutrient?
