Chickens no laying eggs?

[ipbhm]

My 8 chickens of 14th all together are not laying eggs for more then 2 months? Just stop doing their job? I just get one egg every other day. the rest are broody. They don't look sick. And they are not older then 2 years. What happened?
One month I did switch new cheaper food, and that was it. From time I gave them new food they stop laying. So couple weeks ago after they finished that cheap food, I started again on organic, but no eggs still. Now winter is coming, and are they going still to be like this?
Please help for reason whats with my chickens?

I would start by assessing their coop. Chickens like security and to be screened in on all sides at night. Is there an area where it is more open that they are sleeping at night. I actually had this problem with my chickens once and when I addressed the issue they started laying again in a couple of weeks.

Do a quick search on Winter lighting.

Chickens need a minimum of 12 hours per day, not sure of your location.
