Khaki Campbells and egg laying or not

[Tweeza]

I have 5 Khakis, born end of May, and it only seems that 3 are laying. I usually can count on 2 per day but sometimes I get three. They've been laying pretty consistently since about Oct. I know I should be patient but it seems that I should be getting more eggs. They all seem to be hens, no curled tails, I feed them Layena, and they very rarely get to free-range. What are your thoughts?

As the days get longer the egg production will go up. You could supplement their light to get them to lay more, but by February they should stop popping out more eggs on their own.

I have 3 Welsh Harlequins and a runner and they are hardly laying at all now. It has been VERY cold where we are and that will also effect laying.
