We have a Rouen duck who has tried several times to have a nest. Last ones she sat on for 40 days before we moved her and them (we just fenced her all in). She is 2 years old. The last couple of weeks, she is escaping the fence - every. single. day. We re-fenced the duck area with taller fence. Then, we thought she was getting under it, so we put staked it down all the way around and put rocks in an areas that looked questionable. But, still every single day, multiple times per day, we have to catch her and put her back in. She never goes anywhere, I don't think she wants to get too far from her friends. We have not been able to figure it out, no matter how long we watched, she always did it when our back was turned (and I am convinced that she is laying another clutch somewhere on our 10 acres). Well, yesterday, I saw her. She CLIMBED THE FENCE. I watched her flap her wings, and then use her beak and feet to actually climb the 40" chicken wire fence and get out. I was dumbfounded. So, short of putting a 10 foot high fence around her (which might not help anyway!), I am wondering if we trim her flight feathers if this might keep her in? What do you all think? I am worried because at some point she is going to go hang with her eggs and we won't be able to lock her in the pen at night with everyone else (their "day" area is what she is escaping from) and we have a lot of hawks, coyotes, eagles, mink, etc., in the area.
