I have about 16 chickens that for the past few months gave me each an egg every day give or take a few. The were free range on my 20ac property till about a week ago when I started keeping them in the coop and the run because it's getting colder and predators have been on the property more often as it's getting colder. Now they have almost stopped laying?? I get one maybe at most 3 a day there feed is full have a heater for the water.. Even put a few squares of hay in with them.. But still not really laying.. Any ideas or advice?
