I had multiple family members with chickens, so I was around chickens going back to the 50s. I got my first chickens of my own as an adult back in the 70s. Around 20 years ago, I started getting into a lot of different heritage breeds. Sometimes I had a couple dozen chickens, sometimes closer to a hundred, sometimes just a few for the household. Sometimes I sold eggs or raised meat chickens. A couple of times I lived where I couldn't have chickens, but that was only for a few years.
For me, having chickens is a bit like having a dog. I like living with dogs and I like living with chickens. Sometimes I have more or fewer in number. At different times I participate in different activities with them. My lifestyle may change at times, but I usually manage to have dogs and chickens in it.
