Hi Mary!
I'm guessing I have maybe 80 birds, divided between the two coops.
The red coop/yard is all bantams and 3 baby geese. The red coop is 8x8 and the attached covered yard 10x30.
The larger coop/yard is where the standard sized birds are, along w/ a handful of ducks and 2 geese. That coop is 10x16, with a 10x16 covered yard and attached 30x50 (or is it 30x60? I can't recall off-hand) run.
Once the garden gets bigger and it's not so easy for the birds to pluck the garden clean, they get to free-range in the back yard during the day.
The blue tubs are what the molasses/mineral supplements for our cattle come in, which we put out for the cows once or twice per year. Once the tubs are empty, I drill holes in the bottoms and use them as planters. In years past I've used them for tomato, but this year I'm using them for cucumber, loufa, and small cantaloup.
