Hi, I just wanted to saying I've been watching your post and hoping that somebody would respond. I too am planning and preparing for a couple of Pekins or Campbells as a first timer and trying to pick up all the info I can. Good luck!
I have an Eglu and 3m run, have just ordered the Omlet 21m fence and I'm preparing an area for them and investigating ground cover/substrate. Thinking 60% pea shingle and 40% hardwood bark. Also planning a light and easy to empty/refill water bucket or trough, and a shell paddling pool from Argos.
Have a reasonably large garden so planning to let them FR when I'm around.
