In Canada about 3 million farm animals die en route to slaughter every year. Most are chickens.

After a life in dark barns with little human contact, transport is emotionally stressful. Birds get dislocations and broken bones during catching, loading, and unloading. Many chickens overheat or freeze to death on the truck.

Birds are grabbed 3-4 in each hand by their fragile feet and roughly thrown or shoved into tight crates

Both meat birds and laying hens have their food withdrawn up to 8 hours prior to transport, and lights are lowered. Meat birds are herded into a fenced area before catching. Laying hens are grabbed from inside their cages. The weak birds are vulnerable to injuries.

A crate is filled every 7 seconds! Humane handling is impossible. Birds suffer dislocations and broken bones due to rough handling.

During careless loading, birds can get their wings and heads crushed in the crates

Mechanical catchers can be more humane but are also prone to abuse. The emphasis is speed, not animal welfare. Images from Mercy For Animals videos

Amsterdam-based Eyes on Animals shows current and improved ways to catch and load chickens in a short video called Calming The Catch (the better way is shown towards the end):

Some birds fall over from exhaustion. Birds suffer further injuries during unloading.

Birds arrive exhausted and injured. Some like this one are on their backs, barely alive.
