It should help some......
Starter feeds
Feed newly hatched chicks a starter diet until they are about 6 weeks old. Starter diets are formulated to give proper nutrition to fast growing baby chickens. These feeds usually contain between 18 and 20 percent protein.
It is not necessary to feed "meat bird starter" to young layer chickens. Diets formulated for starting meat chickens are higher in protein (22 percent) to maximize growth, which is not necessary or desirable for egg laying chickens and is higher in cost.
Grower and developer feeds
Once the birds reach about 6 weeks of age, substitute a grower feed for the starter. Grower feeds are about 15 or 16 percent protein and are formulated to sustain good growth to maturity.
After about 14 weeks of age, you can substitute the grower feed with developer feeds if they are available. These feeds are lower in protein than grower feeds (14 to 15 percent) and are formulated to prepare young chickens for egg production. Note: These two feed types are virtually interchangeable; either one can be fed to chickens between 6 weeks of age and the beginning of egg production.
Layer and breeder feeds
Once your chickens begin laying eggs, you can choose between layer and breeder feeds. Your choice of feed at this stage depends on how the eggs will be used.
Layer feeds are formulated for chickens that are laying table eggs (those used for food). Layer feeds contain about 16 percent protein and extra calcium so the chickens will lay eggs with strong shells. Start feeding layer feeds at about 20 weeks of age or when the first egg is laid, whichever occurs first.
Breeder feeds are formulated for chickens that are producing eggs for hatching. These feeds basically are layer feeds containing slightly more protein and fortified with extra vitamins for proper chick development and hatching. However, use of breeder feeds is somewhat questionable for the small flock producer, since the increased cost may not be justified by the potentially slight increase in hatchability.
You also may give both laying and breeding chickens access to ground oyster shell. Some high-producing laying birds may require the extra calcium provided by oyster shell, even though the prepared diet is a complete feed. The need to feed oyster shell can be determined by shell quality. If eggs are laid with thin shells that are easily cracked or shells that are rough with almost a sandpaper feel, oyster shell may help to increase shell strength and quality. When feeding oyster shell, provide a separate feeder allowing free choice feeding on oyster shell.
Medicated feeds
Most commercial starter diets are medicated to prevent common yet serious diseases in chicken flocks. Medications are less common in grower or layer diets. Feeds that contain medications are labeled as such.
Check the label for warnings concerning the medication used in feeds. Withdrawal dates will be indicated on the label if there is a risk of the medication's presence in the eggs. Feed medications are highly researched and regulated, so you can be confident that the eggs are safe to eat if you follow the label instructions.
If you wish to use nonmedicated feeds, they usually are available or can be ordered. However, in some cases, mortality levels, especially in young chicks, may rise to unacceptable levels if nonmedicated feeds are fed.
Water
Water is the single most important nutrient that chickens consume. Therefore, it is necessary to provide adequate amounts of clean, fresh water daily during growth and egg production. Chickens will drink between two and three times as much water by weight as they eat in feed. Their consumption of water increases in warm weather.
Scratch (grains)
Chickens love to scratch. They use their feet to disturb the litter or ground to find various seeds, greens, grit, or insects to eat. Feeding scratch grains can promote this behavior, which gives the birds exercise and keeps them busy. However, feeding scratch to chickens is not necessary when they are receiving a complete diet.
Scratch feeds usually are cracked, rolled, or whole grains such as corn, barley, oats, or wheat, which are relatively low in protein and high in energy or fiber depending on which grains are used. When fed in concert with prepared feeds, they dilute nutrient levels in the carefully formulated diets. Therefore, you should provide scratch sparingly. A general rule of thumb is to feed only as much scratch as the chickens can consume in about 20 minutes, or about 10 to 15 percent of their total daily food consumption.
When feeding scratch, also provide an insoluble grit so the birds can grind and digest the grains properly. If the birds have access to the ground they usually can find enough grit in the form of small rocks or pebbles. Otherwise, you can purchase grit. Oyster shell cannot be substituted for grit because it is too soft to aid in grinding.
Now with that said this is what I feed...
Starter from 1 day to 5 weeks old my starter is a medicated feed with 28% protein
Grower from 5 weeks old till they start to lay eggs my grower is 21% protein
Layer when they start to lay eggs and it has a 20% protein
Scratch Grain I dont feed till they are laying eggs and then I use a 16% protein all grain pigeon feed with corn for scratch.
Grit I start grit when I start giving scratch grain...
