I bought "paintings" of chickens (it's some kind of print process -- but they are on canvas). Also I got a cast-iron stepping stone/trivet that's been screwed over a vent hole in the gable. Another thing I got was a weather vane garden decor item, like a shepherd's hook -- it's going on top of a cupola, where a weather vane belongs.
Here are some interior notions -- stencil, wall paper borders, a valance or curtains at the windows, a plate rack, a clock. You might consider a chicken theme or an over the top formal theme -- Victorian, French country, English country.
For the exterior there are Shutters, window boxes, hanging plants, potted plants, garden stones, decorative molding, fretwork, concrete figures, chairs.
As for paint -- on the interior if you paint a pale terracotta or a warm-golden-peach it will look clean and reflect light but will conceal dirt better than white. On the outside, follow your instincts.
We need pictures.
