The sheep farm I'm talking about here belonged to my sister in law - we would visit from time to time and sometimes I got roped into doing some work. I liked riding the four wheel drive motorbike around, but often ended up left doing things I had no idea how to do like loading giant lambs into a trailer.
The dairy farm belonged to our raw milk supplier, and we visited that regularly as well.

Both farms have since been sold so I don't know what they do now.
Neither resembled your vision of hell description - if that was how things were I never saw it - and they weren't hiding anything. No it wasn't paradise, it was farming, but like many services essential to human existence it had certain realities to deal with.

Of course they're not gonna show you the bad stuff. That's not good for business. Go on the day they take the babies away from the mothers and report back.
I had a thought, that could be a post, but I'm a bit tired for that so here is a meme...
LOL that's pretty funny yes. I too have a sick sense of humour, not many vegans do tho. That's prolly why you put up with me
