Nice outhouse. (Just kidding, it'a a very nice coop). The Tyvek wrap reminded me of a house I was doing some work on. An older gentleman walked by and said, "You put that stuff on upside down, the letters have to be the other way." He was dead serious so I told him that since heat rises, if you put this stuff on upside down then the heat goes downs and warms the floor. "That's a good idea" he says and walked away.
If you have ever eaten fish sticks, fish nuggets or any fish from a fast food resturant, it is all trimmings run through a grinder then formed (perhaps with a worker's finger or 2).if you are worried about it run the trimmings through a food grinder first.
there is lots of healthy stuff in fish. I have thought about running my fish trimmings through a grinder and feeding them to the chickens, I usually go to lake michigan for salmon or lake erie for walleye so on a good trip I could have 10 pounds of carcasses.
