Grower Feed Formula & Nutritional Composition

What is Grower Feed?

Grower feed is the type of feed given to laying chickens from when they are 8 weeks old until they are ready to start producing and laying eggs (usually between age 18 weeks and 22 weeks. Once the young chicks are 8 weeks old, you will have to switch their diet to grower feed.

As its name implies, the grower feed will stimulate the growth of your birds in a healthy way. It is specially formulated or made for pullets to prepare their body and reproductive organs for the egg-laying activities. It is the next feed given to young pullets after brooding.

Although, some poultry farmers give grower feed to cockerels, broilers, turkeys, ducks and rabbits. Yes, there is no harm in serving the feed to them, but it is important to ensure that the nutritional requirements of these animals are met. As soon as the young pullets start laying eggs, you should prepare to switch to the layer feed.
