Should you withhold food before transporting your bird? What a study on chickens shows
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Some owners remove food before a trip, to avoid mess inside the carrier. A study published in 2005 by Nijdam, Delezie, Lambooij, Nabuurs, Decuypere and Stegeman in Poultry Science shows that this gesture is not physiologically neutral (, doi 10.1093/ps/84.7.1146). Our other travel guidance is gathered in the bird travel and safety section.

The context: routine feed withdrawal in poultry farming
In broiler farming, feed is withdrawn several hours before transport to the slaughterhouse, to limit digestive residue during the trip. The authors measured the hormonal and metabolic consequences of this practice, comparing several withdrawal durations before the transport itself began.
Corticosterone rises at withdrawal, before the trip even starts
A notable finding: plasma corticosterone, the reference stress hormone in birds, already rises during the feed-withdrawal phase, before transport begins. Stress therefore does not come only from movement, noise or handling — food deprivation itself triggers a measurable physiological response, which then adds to the one caused by the trip.
An industrial context far removed from a trip to the vet
This study concerns broiler chickens headed for slaughter, with withdrawal periods of several hours followed by transport lasting several hours as well — nothing like a fifteen-minute car ride for a vet visit or a holiday trip. It nonetheless points to a principle worth transposing with caution: withholding food out of caution before a short trip has no clear sanitary benefit and could add an unnecessary stressor, when a healthy bird handles a few crumbs in a properly equipped carrier perfectly well.
What remains good practice
Removing open water bowls that would spill at the slightest braking still makes sense, as does favoring a seed holder fixed to the walls over a loose bowl. Guidance on equipping a travel carrier is detailed in our article on carrier or bag for a bird. Before a long trip, it is better to offer a normal last meal than to impose a fast that, according to this study, brings no calming benefit and could even add stress.
Frequently asked questions
Should food still be withheld before a flight?
Airlines sometimes impose their own rules on this point; absent a specific requirement, a healthy bird does not need to fast for a trip of a few hours.
Does withholding water raise the same concern as withholding food?
The study does not separate the two precisely, but dehydration is a distinct and potentially faster risk in a small bird; access to water right before departure remains advisable even if the container is removed during the trip itself.
