So, I don't own chickens and I'm not really keen on livestock. I am an informal observer of a particular flock of chickens. Here's the story: A few decades ago a farmer had some chickens (40 give or take a few?). At some point he left or died and the chickens were abandoned to find their own way. Times changed and the farm is long gone. There's a busy intersection with a gas station, a shopping center, a Walgreen's, and a Peet's Coffee. The descendants (dunno how long chickens live) tend to hang out at the pharmacy and cafe where there are some bushes and people leave food and water for them. In fact, they're kind of an attraction. I like to watch them and it gets me thinking. How long will the flock last? How many chickens do you need to avoid inbreeding? And many more. Anyways, I thought this forum might have answers or advice for me. Plus, you're the ones most likely to understand my... Hobby? Of chicken watching.
