Chick up to 36 hours without food

When they leave the egg, chicks can eat no more than a day and a half without food and drinks. If this takes longer, it has adverse effects, then more chicks will die and that indicates a possible impairment of well-being.
This is shown by a study by Wageningen Livestock Research and Adaptation Physiology that was carried out after protest by Wakker Dier (this organisation active for keeping animals with respect)
In commercial poultry farming, eggs are hatched in a incubator at a hatchery. Only when the majority is released are the chicks collected, this takes on average one or two days. Then the chickens are sorted, vaccinated and transported to the farm where they will stay until the slaughter.
'When the chicks have to be transported over a longer distance, it takes three days for the chicks that have first come out of the egg before they can eat or drink something', says Ingrid de Jong, animal welfare researcher at Wageningen Livestock Research. According to her, this is rarely the case in the Netherlands, because most chicks are placed there on the farm within 36 hours of their outcome.
Court case
Wakker Dier finds it unacceptable that chicks get no food and water when they come out of the egg and filed a lawsuit against the Ministry of Economic Affairs because, according to her, refraining from food and water affects the welfare of the chicks. The Ministry asked the Wageningen researchers whether this was indeed the case. De Jong and her colleagues conducted a thorough analysis of the available scientific literature. This showed that chicks that do not eat and drink for an average of two days (36-60 hours) lose weight: probably because they dry out and get less food. It also had adverse effects in the long term. Up to the age of six weeks, when a standard broiler was slaughtered, the chickens grew less well and more died.
