Going bigger overall - bigger coop, even more ventilation, bigger run, etc. It's plenty big for the birds we have/anticipate having, but everything's just easier with more space to move around in.
Otherwise, the thing that would make things a lot easier would be if hubby had time daily to help out. He pitches in with cleaning and feeding on weekends but on the weekdays it's just me. Any installation work from adding an apron to installing the coop cam, plus the routine maintenance work and yearly clean outs, is 99% on me - which is mostly terrifying if you imagine someone afraid of heights up on a ladder with power tools, and 10 feathered dinos standing under the ladder waiting for me to fall and crack my head on a rock so that I can be their dinner.
