Hi. My 4 hens, which are 2 Rhode Is. Reds, 1 Delaware and 1 Bantam (I think) are 18 weeks old today. So in theory they may start laying eggs in 2-3 weeks time. Which is also coinciding with the onset of fall/winter. I live in seattle where we are affected by limited sunlight hours during the winter. So my question is should I put a light on timer to trick them into thinking there's more sunlight then there actually is or will they still lay eggs just not as many through the winter. Thanks!!!
