Hello I have 3 hens 1 RIR 2 Hybreed's about 30 or so weeks old. Production of eggs was on the upswing when they started a few weeks ago my RIR was the last to start . I was getting at least two eggs a day up to last week. Now i'm maybe getting one a day . I don't know if the shorter days are having anything to do with it since the sun is setting at 730 pm instead of 900 -930 pm ? The daily routine has been the same no change in feed or anything. Really baffled on this one. One thing I did change was closing the pop door at night to try and keep heat in for them / drafts down. I don't get around to letting them out untill 8 am . They do have a window so they can see the light outside. Any help or info would be great . thanks!
