Thanks very much for the advice, they are working on adding insulation under the roof atleast where the birds will be roosting. It's been SO cold up here not much work being done. We have been waiting for a break in the weather so they can stain it but I think we may consider just staining it in the Spring considering this Ice Age we are inScanned that photo again and noticed something I would suggest be changed, but may already be too late. I'd have them put insulation under the metal roof on the back part above the roosts. Otherwise, you will get condensation in there and have water dripping on the birds. That is an issue that has been known even in Woods time.....his plans call for boards as roof decking, covered by felt paper and asphalt shingles. It was known even back then that uninsulated metal roof in livestock buildings was a mistake. Not critical over the front scratch shed, but I'd want it over the back part under the monitor.
As for what type of insulation, I'd have them use 1/2" foil faced hard board polyiso stuff, with foil side out and white side in and have them place it over the purlins and under the metal. They will need about 3 sheets of it.
In addition to helping with the moisture and condensation, insulation under the roof creates a "thermal break" to prevent radiant heat from being lost to the outside. The birds themselves are the source of the heat. With a load of birds, coop will be warmer and dryer inside with insulation under the roof......no supplemental heat needed.
I have an "Amish" built horse barn, which is very good, but either they didn't know to put insulation under the roof, or were told not to (to save on cost), but either way, if horses are left inside, it will literally rain inside and leave a lot of stuff wet.
