Right then, the full process of butchering chickens! This will be long, as there are a surprising amount of steps and I’m also a bit of an over explainer…
The chickens arrive on lorries in plastic crates, the crates are placed in the gas chamber and the birds are gassed. Once they are dead, they are removed from the crates and hung by the feet on the shackles. They are checked, and if they survived being gassed, they are dispatched by hand and then disposed of as waste. We’re not allowed to process chickens that have been killed by hand.
They travel along in the shackles and go through a blade that slits their throats and then they bleed out which takes approx 90 seconds, there is a person standing by at all times to make sure they’re bleeding properly. After this, they get dipped into boiling water, this opens up the pores to allow the feathers to come out easier.
I never saw where the plucking happens so I’m not sure exactly how that’s done. But after they’re plucked, they go into EV (evisceration) where the feet, heads and innards are removed (but plenty get missed, we always end up with random hearts, livers, stomachs and the occasional head etc travelling along still attached to the chicken after they get into the factory!). Necks are also supposed to be removed but we get a lot of those through too!
After EV they go through two chillers, a water chiller and a blast chiller (actually there might be a third but I can’t think what it’s called!)
And then they arrive in the factory. The first thing that happens is, they go through a set of blades that slices off the wings which drop to a belt below, then a blade that slices part of the way under the breasts to start to separate them from the legs. Then another blade that fully separates the body from the legs, then the legs (which are still joined at the hip) go through one last blade that splits them, they’re then pushed off the shackles by a metal bar and they drop to another belt below.
The wings travel along a belt where they’re graded and packed, same for the legs. The body (which is now just a torso) travels along another belt where they are picked off and sat on cones (called the cone line), where the breast meat is sliced off by hand by the cutters. 4 people, 2 doing right sides and 2 doing lefts. Each cutter has a table to the side of them where they place the breasts, a trimmer stands at each table and rips off the skin, trims all the bad bits off and chucks them onto yet another belt where they travel along and get graded.
The empty carcass is then lifted off the cones by two bars where it falls down onto yet ANOTHER belt where the skin is also chucked, (there are SO MANY conveyor belts!) where it all travels along and is sent into a giant mincer where it’s ground down into… nugget/hotdog/pie etc fillings.
I THINK this is everything! I’m not sure if this is odd or not, but the factory where all of this happens (after the chillers) doesn’t really smell bad. It smells vaguely of sweaty feet but I’m not sure if that’s the chicken or from all the people in wellies 🤣
