Okay this may sound either weird or cruel, but it's just for curiosity sake I don't plan on doing it. My coop is 100% covered so don't worry I've read about people pinoning ducklings, other waterfowl, or baby quail, but I haven't seen it for chickens other than in the Storey's guide. I'm curious if anyone does this with their chickens. I assume that it's done for waterfowl because they are more likely to feel the urge to migrate and be GONE and quail would similarly try to fly away if given the chance whereas chickens have the instinct (usually) to come home to roost and while they may get some height and distance for a short time, they can't maintain it. I'm not looking for people to say how terrible a practice this is, please, I'm just wondering if anyone does it. Also, as a side question: Everything I've seen says to use shears to pinion a duckling. In the movie "Fly Away Home" the animal control officer was going to do it with nail clippers. Would using nail clippers even work or would it be too shallow and not reach the joint? Thanks for any input!
