we three hens, 4-5 mths old. We are hoping they will start laying eggs soon, if not they go back to the place we got them from!!! This winter has been pretty cold for us in the South, so we purchased a heat lamp for the coop. The hens, Minnie, Daisy, Henrietta love it. Our question or concern is with the light on all night does this hinder them from laying eggs once they start? We have made their nesting boxes, so far they seem to ignore it.
