Summer heat distress
has not been resolved

During heat waves, hens will eat less
and produce fewer and smaller eggs.
This issue is best addressed by proper
facilities and management, but nutrition
can also play a role. Primary attention
should be paid to feed electrolyte balance, but certain additives, especially
through the water, can be administered
to alleviate the problem. Feeding during
cooler hours (night) is not an easy proposition since it interferes with the egg
formation cycle.

The dilemma of a
prelayer diet

Most farms feed a prelayer diet
that is high in calcium to ensure early
egg production does not deplete hens,
but some don't because this might
predispose hens to early renal failure
from calcium over-dosage. A high calcium prelayer diet also contributes to

in most situations, but they are very
expensive.

6

Sticky, wet, dirty litter

Water overconsumption combined with viscous cereals in the feed
cause sticky droppings that refuse to
lose their water through evaporation.
This is not such an issue in cage-housed
layers, but when they are housed on litter it becomes a major issue that affects
hen health and welfare and gives issue
to dirty eggs. Understanding why hens
might consume more water than they
need (feed electrolyte balance and protein are the major nutrition issues) and
addressing feed viscosity seem to resolve
this problem, unless it is a major disease
problem.

Finding the right yolk color

Pale egg-yolk color is undesirable in the fresh-egg market, whereas
an overly red one is also suspicious.

Pellets, mash or crumbles?

This is a much-asked question, and it really has no single answer
apart from the recommendation to test
what works best under the conditions of
each farm. Mash is cheaper, but it can
separate. Pellets are recommended for
low-appetite strains, but they are more
expensive. Crumbles seem to work best

Feather picking

This remains a problem in caged
layers, mostly out of boredom, lack
of space or both, but it can also happen in cage-free hens if their diets are
low in protein or specific amino acids.
Checking the mineral and amino acid
profile of a diet will quickly reveal if this
is a nutrition problem or something that
