Such a flock can produce eggs having a selection of shell colors.
Many dual-purpose breeds, such as Plymouth Rocks and Rhode Island Reds, lay eggs with light brown shells. Maran hens lay eggs with dark, chocolate-colored shells, which have become popular lately. The chickens produced from these crosses have beards and muffs rather than the tufts seen on Araucanas, and they have tails.
If bred to the purebred standards, such a cross will result in an Ameraucana, which lays eggs having blue-green shells. Obviously, you can choose from several breeds. When making your decision about which breed or breeds to raise, keep in mind that commercial-type hens may give you a higher level of production initially, but other breeds tend to lay for more years.
Pullet Management It is important to manage pullets correctly, especially in the areas of nutrition and light management, because correct management will affect the level and quality of egg production once the birds start to lay. Also, the hens may lay smaller eggs throughout the production cycle.
When raising pullets from day-old chicks, brood the chicks as you would any other type of chick.
For future laying flocks, keep in mind that light management is important from brooding through all laying periods. If you download pullets ready-to-lay, you should ask how the pullets were raised with regard to nutrition and light management so that you can adjust your subsequent management of the flock accordingly.
For example, you may have to delay light stimulation if the hens are too small.
Raising Chickens for Egg Production
Light Management for Year-Round Production Chickens are called long-season breeders, meaning that they come into production as days become longer. That is, they start producing eggs when there are more hours of light per day. Typically, day-old chicks are kept on 23 to 24 hours of light per day for the first few days to make sure that they are able to find food and water, especially water. After that time period, you should reduce the number of hours of light per day.
If you are raising the birds indoors, you can give them just 8 hours of light per day.
If you are exposing them to outdoor conditions, you are limited by the number of hours of light per day in your area, of course. When the pullets are ready to start laying, slowly increase the light exposure until they are exposed to about 14 hours of light per day. This exposure should stimulate the flock to come into lay.
To keep the flock in lay year-round, you will need to maintain a schedule of at least 14 hours of light per day. You can increase the amount of light slowly to 16 hours per day late in the egg production cycle to help keep the flock in production. For most flock owners, this strategy involves providing supplemental lighting.
Also, you can get a light sensor so that the light bulb does not come on when natural daylight is available.

By using such a device, you minimize your electricity use. The supplemental light you provide does not have to be overly bright.
A typical watt incandescent light bulb works fine for a small laying flock.
Michael Darre from the University of Connecticut. Nutrition Chickens of any type and age require a complete, balanced diet.
Feed mills assemble the available ingredients in combinations that provide all the nutrients needed by a flock in one package. Some producers mix complete feeds with cheaper scratch grains, but doing so dilutes the levels of nutrients the chickens are receiving, and nutrient deficiencies can occur.
Nutrient deficiencies can adversely affect the growth of pullets and the level of production of hens. It is also important to feed the specific feed tailored for the type and age of the chickens you have.
Confining chickens to cages is a welfare problem, as has been thoroughly demonstrated for laying hens used for egg production. Caged broiler chickens may suffer from poor bone strength due to lack of exercise, feather loss, and restriction of natural behavior.

There are also potential food safety concerns associated with the use of cages. While cages may provide an economic advantage in some geographical regions of the world, the severe, inherent disadvantages should also be considered before cages are more widely adopted in the global broiler chicken industry. Abstract In most areas of the world, broiler chickens are raised in floor systems, but cage confinement is becoming more common.
The welfare of broiler chickens in cages is affected by movement restriction, poor bone strength due to lack of exercise, and prevention of key behavioral patterns such as dustbathing and ground scratching. Cages for broiler chickens also have a long history of causing skin and leg conditions that could further compromise welfare, but a lack of controlled studies makes it difficult to draw conclusions about newer cage designs.The hens usually lay eggs either on the floor of the coop or in baskets if provided by the farmer.
Otherwise, you will have to break up any frozen water on a regular basis.

After that time period, you should reduce the number of hours of light per day.
