What? There is something busier and more important in your life than keeping US updated??I forgot to come back with pics of the new coop and set up!
Looks good, not sure why H would want to take her kids into D's nest but yep, seems you need to keep the coop runs separated for now. I would definitely get rid of any visible foam, chickens like to eat it. I don't know what would make it attractive to them. They will also eat rigid insulation.
Bent the tiles over their legs? I can see where that would make for a lot of NON uniformity. But, I guess it was a tool they always had available.
