I have 5 chickens one is moulting right now so only four are laying . I heard that you can increase the egglaying by adding more light so they have more daylight hours . So.......... I put up a stran of Christmas lights ( white ) in their coop. I added hours in the Am they come on at 4AM and shut off at 730AM them come back on at 4pm til 730pm . My concern was putting heat into the coop . I dont want heat in there do you think by adding the lights that there would be too much heat in there for them ? Or should i just rip them out of there ( the lights ) .
