Hello everyone!! How many of ya'll out there use heat lamps to make your chickens lay eggs during the winter? I have never used heat lamps before and my chickens have always laid during the winter.... a few laid during their molts and laid during severe ice storms. But this year they are getting older and 2 have really slacked off laying this winter. What did our great great grandmothers do when there was no such thing as heat lamps? And do my 2 older hens need a heat lamp now that they are beginning to age?
