We are in zone 8, on the east coast. We aren't supplementing light, so I was expecting a drop. We have 4 hens, all arouND 7-8 months old. Our buff orp hasn't laid in 2 weeks and our wyandotte is laying once every 3-5 days. Rhode islands are about every other day, which was more what I was expecting. I've looked everywhere, can't find a pile of hidden eggs, and they appear completely healthy. Is it normal for the larger birds to take a very big break? I was thinking about adding some heat (just the tin can, closed with a light bulb in it) or wondering if I should be adjusting their food intake, or if I just need to put a tarp around the coop, or if this is normal.
