Your coop is gorgeous! I understand not wanting to do a new build when you spent so much time and money on this one. One thing I've found, is that you can use chicken wire to separate out areas within the coop. It might be possible to separate out the coop and run, so Loretta has her own space. Chicken wire is cheap, easy to work with, and easy to attach to walls, floors, etc. - you can frame it out by using some wood and stretching it across. Disposable when you're done, but doesn't break down in the weather. Not predator secure, but great for separating out areas within the run and coop. I use it in combination with a garden gate (wire frame) to section off part of my covered run, and to protect broody hens when they make a nest outside the coop (in the covered run).
