This is a question I've been pondering for a while. Maybe I have too much time on my hands, but I find it both mysterious and amusing. Please don't take it too seriously, it's just a fun thing to think about and kick around a little bit. Okay? It seems that people today go to much greater lengths to feed and care for chickens. For instance we freeze their water, set up multiple fans, regulate their feed and cook for them; we buy crushed granite grit rather than using whatever is in the area, etc., etc. Of course I understand that better care is a good thing, and I don't have anything negative to say about taking really good care of them!!! But I keep wondering, how did our grandparents and great-grandparents manage to keep healthy productive flocks before electricity and scientifically engineered everything else? How did the flock stay cool, find the grit they needed, and eat healthy? Are today's chickens less hardy? Wish my grandparents were still alive to ask, but they'd be 135 years old... literally!
