Alfombra/Carpet/Rug/A bright coloured statement rug is an easy purchase for a nursery of the parent who isn't finding out the gender in advance! It can be chosen post birth and everything else can be neutral without looking like an institution.
Love it! I'd do without the planter though, and make the coop a bit bigger (the whole thing bigger, actually). That would be so much nicer than trudging through chicken poop to get the eggs. xD Cedar Chicken Coop & Run with Planter
