This benefit of feeding crumbs will only be obtained when the birds have access to good quality
crumbs in the feeders. A poor quality crumb can lead to a build up in fine particles in the feeders and,
therefore have the opposite effect to that sought.
From 0 to 4/5 weeks, we recommend using a crumbed diet, after which mash, with a good particle
size, should be used.
It is, however, possible to use a granular feed later, where the grinding is coarser, or even as crumbs,
if need be. However, we recommend using a mash diet from 12 weeks to avoid a risk of under
consumption at the beginning of the sexual maturity if the change is made later.
The bird's appetite for feed depends to a large extent on its particle size. After 4 weeks, we
recommend the following particle sizes:
Particles below 0.5 mm: 15 % maximum
Particles above 3.2 mm: 10 % maximum
At least 75 to 80 % of the particles should be between 0.5 and 3.2 mm. If this standard cannot be
achieved, it is preferable to use a diet of good quality crumbs.
Development of the digestive system
The achievement of good growth and a rapid increase in feed consumption at start of lay depends on
the chicken having a well-developed digestive system, especially a good strong gizzard.
Using feed of good particle size, giving grit during rearing and/or using limestone granules from 10
weeks will all contribute towards good gizzard development.
Between 3 and 10 weeks, we recommend that 3 g per pullet per week (particle size 2 to 3 mm) are
offered. After 10 weeks this can be increased to 4 to 5 g (particle size 3 to 5 mm). It is also possible
from 10 weeks onwards to use a diet 50 % of the calcium is supplied in carbonate form with a particle
size of 2 - 4 mm.
