Okay, I followed the instructions on how to clip wings to the letter: outer flight feathers, one wing only. Clip, clip, flapping chickens bonking into the fence, hooray! None of my Buttercups or Cochins are now able to fly very well. I decided to clip them because the Cochin roos were flying over the 5' fence of their pen and nesting in the neighbor's trees, and the neighbors didn't appreciate it much. First couple of times I put them in their pen with wings clipped, all went as planned. There aren't any perches or sticks in their pen that they could use as stairs, just soft weeds that they eat and trample. Third time, I walked out to check on them...And my biggest Ameraucana was perching on the top post of the fence. She hasn't molted and completely re-grown her flight feathers in the space of one week, I am sure I would have noticed, and anyway I checked. Wing still clipped. She just flaps extra-hard with the other one and wiggles her tail and somehow regains her balance. Okay, my neighbors are already very understanding about five roos. I can appreciate that they don't want chickens free-ranging in their personal yards, so if my monster chickens are to be let out at all, they need to stay in their pen. Any ideas? Help!
