I’m not sure I’ve encountered a rotten egg but I’ve sure smelled a chicken farm but it was a few decades ago. Best I can remember it smells like rat or bat droppings but turned up to 11 with some extra ineffable nastiness that I can’t describe thrown in.
Which reminds me that everywhere has its own problems:
St Kilda was a very peaceful, isolated island for centuries, with major crime virtually unknown. However, as a major nesting place for birds which formed a major part of their diet, the entire island was infused with a nasty birdy smell.
Pig farms are nasty, too. I’ve only come across one once while walking trails out in the county, and we were only near it. We stopped and asked the first person we met because we didn’t know if it was a decomposing body.
When I was growing up, my mother sat me down for a “facts of life” speech.
She explained the different types of shit, and how to use the expressions correctly.
Bullshit is the most-used descriptor. It stinks, it’s everywhere, and it has its uses, but there is entirely too much spread thickly for you to even consider it makes stuff grow, when properly applied.
Chickenshit is semi- liquid, messy, smelly, slops all over everything it touches, rarely has a useful purpose. The mess outweighs any benefit.
Horseshit is bulky, full of seeds so it’s not good for fertilizer, stinks, and in pre-automobile life, was everywhere. This descriptor is best for something that is useless.
When I was a kid I had an iguana for several years, God the shit from that thing reeked! It’s weird because it would be brown poo with like a combination of white stuff that looked like bird shit.
When I was in college a friend gave me three chicks for Easter. As they grew, their shit stank more and more until it was unbearable.
But the worst shit I ever smelled was the mule shit on the trail in the Grand Canyon. I was on the last mule, so was treated to the shit from all the other mules. It was green, and had the distinct odor of ammonia.
