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.
