I'm in the process of building a coop that is actually 4 coops in one with attached runs. The basic design is a 10'x24' building and I haven't framed the runs yet but they will extend out 10' and each be 6' wide. Each interior coop will be 6'x6' and have a chicken door leading to each run, and there will be a 4' wide hallway that'll run behind each coop. The exterior fencing is simple enough and a no-brainer - I'll use 1/2" hardware cloth around the outside of the runs and install a skirt out of the same material that'll extend out 3' all around the building and runs. I'm planning to use this coop/run setup primarily for breeding, so each of the 4 sections will have one cock and my best 4 or 5 hens. Now for the part I have a question about. Is it ok to use regular chicken wire between the interior coops and runs or should I separate them with something like plywood on the bottom 3' or so, so the roosters don't get distracted by each other's presence? I don't want them to be distracted so they concentrate on fertilizing the eggs. I've never raised roosters together in close quarters so I want to make sure the design doesn't interfere with the purpose of the breeding coop. Any thoughts and/or advice would be greatly appreciated. I don't think they'll be distracted and even if they are I could always add the barrier after the fact but I'd rather get it right the first time.
