I have three hens- a silkie and an ameraucana which r six months old and a Brahma which is seven months. No eggs. Weather is turning now,days getting shorter... If I introduce a light to their coop could they still start laying this year or should I not push it and keep them comfy until spring? These r my first chickens- until last week they roamed the property at will and would stay in the coop at night, but one got taken by a coyote last week and so now I keep them in a roomy coop and let them out for just a couple hours a day (but with the recent cold weather they choose to stay in anyways). They r on free choice 16% layer feed and scratch grains, I keep a seperate dish of oyster shells and grit. There r two nesting boxes with soft hay bedding which I change regularely tho they hardly go in there. Is there anything I can do differently to encourage then to lay? If I got another hen that was already laying would that perhaps get them in gear? Not sure where to go from here, thanks for any input!
