Smaller breeds tend to be quite the escape artist. I couldnt exactly tell what your fence is made of. The panels you spoke do work well. I have a Nigerian Dwarf and she is in her own pan that is built with stock panels & she has never gotten out once. I beleive there is a 16' panel goat fence...
It does look like a Golden Comet, I have 4 hens & love them. So easy to work with and this year I only had abut 20 times I only got 3 eggs instead of 4 daily. Good luck.
