Reading through this thread, I've noticed there seems to be a trend of "people who think you need a rooster to get eggs" combined with "and they grew up ON A FARM!" which actually kinda makes sense... when on a farm would you ever NOT have a rooster as part of your flock? It's such a given thing, that "real" old-time farm people probably never saw hens living without a rooster. It's only us small-time back-yarders, folks like me with my 2 or 4 or 5 hens but no roosters because I'm living *right* downtown, that would even think about having hens with NO rooster. So, it's really not intuitive farm-sense that hens can do their thing without a man in their lives.
So, my dad did ask about the rooster thing, very politely ('I just don't understand how they're laying eggs without a rooster'), and I used the whole human-female-ovulation comparison (well, dad, I ovulate every month since I was 15, regardless of what was going on with my love life, and that's exactly what the chickens are doing...) when I realized he was turning kinda green. Oops.
Not sure if it was the idea of his daughter ovulating, or the idea that his favorite breakfast is chicken ovulations, but... yeah.
ETA: I did get one "chickens smell so nasty" from a coworker, who's grandmother kept them. I pointed out that cats' litter boxes smell just awful when you don't clean them often enough, and there's a huge difference between a household with 1-2 cats, and one with 9.
I also got that weird vibe from my mother-in-law who associated growing your own with being too poor to buy store-bought. I just explained that these were very pricey, heritage birds and it was kind of a boutique hobby in these parts, which was true. She accepted that!
