Do you know what do you do if your hens stops laying eggs? There are a number of reasons your egg production is lower than it should be. Some of these reasons are normal things that don't indicate that anything is wrong. Other reasons could be more troublesome and indicate that something needs to be done or corrected.
You need a little bit of knowledge before you will be able to respond or not respond in an intelligent fashion. If you don't understand the issue, how could you possibly fix the issue.
Winter
One reason that will cause your chickens to stop or reduce egg production is simply the season. During the winter hens will stop laying eggs because they aren't receiving enough daylight. This is a natural genetic response and does not indicate that there is anything amiss with your hens. Winter is not a good time for chickens to be reproducing so nature simply regulates the hens to not produce eggs when the chicks would have little chance of survival.
So there is nothing that NEEDS to be corrected. Nothing is broken, at least this doesn't indicate that there is anything wrong. You however, may want your hens to keep on producing eggs during the winter. Heck you may want them to produce more in the winter depending on your food situation. The answer is simple, accomplishing it may or may not be so simple.
The answer is to trick your hens bodies into things it isn't winter by simply supplying them with extra light during the dark hours. If chickens are exposed to 14 or more hours of daylight their bodies will think it is not winter and will continue to produce eggs year round.
This 2-14 hour rule isn't magic. It isn't hard and fast. It depends on the chicken, it depends on the breed. And this mechanism doesn't turn on and off like a light switch. A flock as a whole will slowly start producing less and less eggs until it is reduced to zero. So if you keep track of how many eggs are being produced you can make decisions on why as well as what you are going to do about it, if anything at all.
Age
Chickens lay most of their eggs the first 2 to 3 years of age. But this cannot go on forever. Your chickens can be as healthy as possible and live to be over ten years of age. However, that will not result in them laying more eggs. Why? Because when a chicken hatches they have roughly 240-300 eggs already in them. This number is fixed and good health will not increase this number. Once their eggs are all laid that is it. This usually happens where the hens egg production is strong and then tapers off to nothing.
Diet
Now on to the more troublesome reasons that your hens have stopped or slowed egg production and diet is at the top of the list in a SHTF situation where store bought high quality feed is not an option.
Poor diet can cause the egg production to drop quickly. We are talking days not weeks. A chicken can have a full belly, but still not be healthy enough to produce eggs regularly. As with any animal a chicken requires certain things for them to be healthy. If something is lacking such as protien or minerals the chicken will stop laying and direct those meager resources to the hens own body and wait from conditions to improve before again producing eggs regularly.
So if your chickens stop producing try to incorporate more protein in their diets. Lack of minerals and calcium is less likely to have the same effect. Usually it will result in thin shelled eggs that break easily instead of the hen not laying in the first place.
Water
No water means dead chickens. Obvious right! But it is important to keep in mind that the chickens need water throughout the day and not just when they are in the chicken coop at night. So keep this in mind. Luckily it is an easy fix.
Broody Hen
A broody hen means that the hen wants to hatch her own chicks, so she will sit on top of her eggs until they hatch (usually 21 days). During this 21 day period she won't lay any eggs and this is not what you want.
There are obvious signs to look out for if your hen is turning broody. Watch for her sitting on the nest all day. Watch for her guarding her nest and even the removal of some of her breast feathers. This is done to better incubate the eggs.
If you are looking to expand your flock then this is good. But otherwise it is a behaviour that must be controlled. It will influence the other chickens and can get out of hand quickly.
Prevention is worth a pound of cure! So to prevent this always remove the eggs from the nest as soon as they are laid. And once eggs have been laid evict the hens from the nest box and do not allow them back in.
Once you have lost that battle you will have to break the hen or kill it. Here is what you need to do to fix this issue with a broody hen. Remove her from the nesting box and provide a distraction like food. If she goes back to the nest, remove her again and block access to it completely.
Be sure to make her roost on the roosting branches and not allow her back in the nesting box.
Disruption
Temporary disruptions to the chickens routine can cause them to stop laying. Disruptions can be as simple as new additions to the flock or a big change in surrounding, etc.! A little time is all that is needed to remedy this situation.
Illness
If a chicken is sick, then it is not going to be a very productive egg layer. Refer to the chicken doctor links to address these health issues.
Decision Time
When your chicken stop producing, say from age, you have a decision to make. To cook or not to cook. There are reasons to keep a chicken around that isn't laying.
Older hens are great bug catchers. They can help control weeds in your garden. They are better at watching for predators. They produce fertilizer for your garden. They are better broodies and better mothers!
Hopefully this article can guide you to the right decisions with your flock.
