I found BYC mostly because I was interacting with the ducks at our local lake and wanted to learn more about ducks. I found lots of information here. I even found things about killdeer chicks, too, even though they're not a duck or a chicken, but they do behave a lot like some breeds of chickens. I would like to get my own ducks some day, but I don't know if I'm allergic or if I'll ever be able to afford a place that will let me keep ducks.
I do agree with what a lot of people say about BYC about the fact that people are friendly here. I mean, no, it's not perfect, but there are so many forums where people are complete jerks most of the time!
ETA: My grandfather was an "egg and dairy" man in his younger/middle age and used to talk about chickens all the time. Also, my step-dad used to take care of his boss's chickens, too. So chicken talk is not unusual in my household.
