You are welcome.
And yes, they are some seriously happy cows.
You will notice that the cows are undisturbed by being surrounded by hundreds sometimes up to a few thousand people and that there are hardly any barriers at all.
Nothing happens. Cows are gentle creatures and they are used to humans, so humans are just obstacles which they run around. - It's a completely different matter with bulls of course!
In my childhood it was common to see cows with bras - udder supports to be exact. The udders had simply outgrown the frame of the cows and as a consequence the poors things tended to step on their teets or being stepped on their udders by other cows when lying down. So on with the bra.
Nowadays that problem has been almost bred away and the cows have become bigger.
There were tests a few years ago with cows being issued protective clothing while standing on the field - it may come a surprise to some, but cows tan.
In the meantime the cows enjoy a good working day on the field, eating and digesting and when they feel it's time to be milked, they quietly walk back to the sheds. - Or let it be know that it's milkingtime. When we sit outside in our garden during summers we can tell if the local farmers are a bit slow. The cows know the time, so get a move on!
Fortunately cows, or rather bullocks are not the brightest animals around, so they may be confused and annoyed when going to the slaughter house and animals positively hate new rutines, but hardly scared - and then they die.
It's anotter matter with pics. They are intelligent, perceptive and have a good smell. A slaughter house for pigs is not a place to go, if you are sensitive. So the key is to kill them fast, while they are still confused and before they've figured out what goes on.
You may ask yourselves, what on earth has this to do with the DRF? Well, it's still a part of our culture and the DRF children will have got up close to farm animals and livestock and children ask questions, so this is what they would already be familar with at Christian and Bella's age. - Apart from going to a slaugher house, that's a dangerous workspace.
It is very likely I believe, that Joachim's two oldest certainly will have seen hens being decapitated. A much faster and humane way than at the slaughterhouses, where they are hung up by the feet, electrocuted and then their heads are cut off. Takes some ten seconds at most. But only after a long transport.
Out on the farms, the hen is going happily around on her business, before being picked up and she'll never even percieve it when the back of the axe knocks her out.
As long as you keep a firm hold on the legs afterwards, you won't spook any children looking on. It's when you let the headless chicken loose that you freak out children - and dogs. There is no point in doing that, so only fools and amateurs do that nowadays.
