How many hours of light

They need 12-14 hrs. a day of light. Hmmmm as far as laying this year or next, my guess is they will start later this year, but not too many...you will see an increase next year. EE's (or atleast mine) tend to do pretty well laying into the cold months....

 

Chickens cycles run on light and to a point tempurature. The more light there is-ie longer days- tell a hen that it is spring. This is why the commercial egg houses keep lights on with the temp constant. They are simulating spring which is the optimum time for hens to lay. The father south you are you have a longer lay cycle and the farther north you are the shorter it is. This is not to say you won't get eggs in winter but the amount will be less and your hens will lay more sporatically.
In answer to how much light they need it is 12. I've also heard 14 but 12 sounds more correct to me. This is also why the commercial houses keep them under lights. They get 2 eggs every 24 hours-sometimes three.
As for the average backyard hen, you will see a drop in egg production at moulting time (late summer into fall) and a decrease in egg production throughout the winter (October-November). In spring the hens cycle back into heavy production. In more southern climates this production drop can be not as drastic as those father north who have much longer hours of darkness.
As for your pullets, Im thinking you wont see eggs from them until spring. You might get an egg before then but I think it's getting a little to late in the season. You also might get a random egg from them during the winter.
