during transport, but that chicks can get dehydrated if
their body temperature rises to 41.1 C (106 F) and they
have to pant to cool down.
Meijerhof said that so far, the science doesn't support
the argument that early feeding is better for chick
welfare, but he said that some companies have successfully used the inference that early feeding is better for
welfare in the marketing of processed chicken.

Gerrit van der Linde said
that if you if you feed chicks
in the hatcher, you should
also provide feed and
water in the transport truck.

5 early feeding options
Meijerhof said that early feeding, done either during
hatching or directly after hatching, is being done
commercially in Europe five different ways:
■ Hatching the eggs in the broiler house
■ Feeding in the hatchery directly after pulling chicks
out of the hatcher
■ Hatching in a special hatcher with feed and water
provided
■ Feeding in a conventional hatcher with special baskets
■ Feeding during transport to the broiler farm
Operations that decide to try one of the early feeding
options need to realize that other aspects of their system
for delivering poults or eggs to farms will need to
change. For instance, Meijerhof said chicks fed at the
hatchery, whether during hatch or after processing, will
produce more heat. This means either transport vehicles
will need additional cooling or ventilation or that not
as many chicks should be placed in the chick boxes and
fewer chicks would be transported per truck.
If an operation shifts to on-farm hatching, special
consideration needs to be given to how the eggs
are transported to the farm. The egg shells are not
as strong at 18 days of incubation as they are when
first set in the incubator, so they are easier to break.
Meijerhof said that if 18 days of incubation eggs are
transported directly out of the incubator in boxes, the
embryos will overheat and die. He suggested letting
the eggs cool down to 25 C (77 F) prior to transport.
This shuts down development of the embryo, which

better for chick welfare.

prevents overheating, but it does extend the time before
the eggs will hatch on the farm.

The importance of proper conditions
Gerrit van der Linde, a senior poultry specialist at
Heering Holland, said that you need really good
temperature, humidity and carbon dioxide control in the
truck if you deliver the eggs to the farm straight from
the incubator. If you feed in the hatcher, you should give
feed and water in the truck, and if you don't, then you
need to get the chicks on the farm and on feed and water
within four hours. You always need to provide light to
stimulate the chicks to find the feed and water, whether
in the truck, hatcher or on the farm, he added.
Meijerhof stressed that early feeding isn't as simple
as putting feed and water on the sides of a hatcher
basket. Chicks that hatch in the middle of the basket
must be able to move through egg shells, unhatched
eggs and other chicks to make it to the side of the
basket to find food and water. It is a smaller version of
the challenges growers face in getting chicks to move
and find the feed and water in the broiler house. ■
