I can hook you up with some ducks if you want some first hand experience
We've also got chickens, including a roster. I'd happily give him away right now. The more the prick crows at stupid hrs of the morning, the getting closer he gets to being turned into a roast. We've tried a few things to keep him quite, but he just can't help himself (I don't actually blame him; he's a roster, what do I really expect?). The latest thing we have is a collar. The premise being, if we restrict his ability to puff his neck out, he can't make a racket. I thought it sounded a bit cruel myself (he shits me, sure, but I'm not an arsehole about it). When my wife told me it was called cock ring (seriously), I just said collar the little bastard (after i stopped choking on my own laughter that is). I nearly choked again when my son (the one on the autism spectrum) asks what a cock run is.
Anyhow, Roster, with his own cock ring, if you want to experience first hand how awesome birds can be.
