We have 8 hens 4 RIRs, 2 Black Australorps, and 2 EEs - in a tractor with attached run. This is our first year with hens, so we got started late (we were told) trying the light thing to keep them laying through the winter. We didn't want to drag an electrical cord half way across the yard, so we installed 2 solar spotlights - one on each side - directed into the coop "window." The hens turned 1 on October 7, and during the summer in the full thrust of our longest days, we actually got 8 eggs/day, but generally speaking we've averaged 6/day since they started laying. Initially, the light seemed to do the trick, but then the eggs started to drop off, until we went for a couple of weeks with no eggs at all. I just figured the light hadn't worked and we'd try something else next winter. Well, about a week ago, we started getting eggs again...first 1 a day, slowly increasing so that we've gotten 4/day for 2 days this week...all while it is getting colder and the days are getting shorter. I want to get more hens, but I'd like to get more who would be most likely to keep laying through the winter. Is there any way to tell which of the hens is laying the eggs I'm now getting?
