Thank you for being descriptive with your answers, it gives new people an understanding for cause and reason of situations involving chicken keeping.Hey there. I was acctually really surprised when I started reading this thread, with all the different answers your getting. And also with some information that's being given to you as well.
So the first answer...is YES it is completely normal for hens to slow down...and sometimes even STOP laying in the winter months. Of course some places are colder than others and different regions will be effected differently.
Here is the simple and educated answer to your question:
During the colder weather(winter), nature takes course and the hens internal clock tells them first of all that their baby chicks won't survive in the cold and dark. Hens also know that their bodies will use extra energy in the winter for their bodies to stay warm and survive. Energy they would otherwise be putting towards laying.
So they stop producing.
This is also the time of year hens will naturally rest. If given the option to rest, they will produce eggs longer. It's just nature. However lots of people still decide to keep their hens laying through the winter to feed their family. Like me...
It is not unethical to do so....the only thing we do to keep them laying, is provide them with everything they need. Three essentials...
Food, Heat, Light.
The most important...contrary to what some are telling you on this thread....is acctually food and water. Their food and water intake will sometimes even double....depending on the breed and the temperature, if you don't limit them. This helps them with that extra energy they need to stay warm. Which is the most important And then also that extra energy we want for them to keep laying for us .
Then light.... You need 12-14 hours of low wattage light to keep your eggs laying. I keep my light on from 8am until 8pm. I don't even turn it off at all during that 12 hours. I barely see a difference in my electric bill.
And then last...is heat. Again contrary to what people are telling you...loss of heat will stop them from laying, because hens know their babies won't survive in the cold. AND on top of that...the hens use their physical energy for staying warm. And often don't have enough energy left for laying the eggs. So if you can somehow make your coop warmer....you will eliminate that problem. I live in Canada where it gets cold for the winter and lots of snow for at least 4 months. All I do is insulate my coop walls with hay. I stuffed it right in until no more could be stuffed! And hen I put plywood up on the walls on the inside of the coop. I used plastic poly on the outside of my coop...before I put up the plywood to reduce the cold as well. The chicken coop floor is earth, so I lay about a full foot or more of hay on the ground as well. And lots and lots of hay around the coop for them ro cuddle up and be cozy.
I'm going to leave a link at the end of my message to a site that explains all of this. I really hope that my information was helpful. Please let me know if you have any other questions at all.
