A faint barnyard note drifted up the afternoon I cut open a fresh bag at my zone 6 raised bed by the back fence. It was milder than I expected, and a day after I watered it in the air was clean again. The feather meal smell is real, but it does not stick around. So the short answer is no. It does not smell bad in any way that lasts, and you can use it close to your house without worry. Your nose will catch it for a moment, then forget it.
The odor comes from where feather meal starts. It is ground poultry feathers, so it carries an animal-protein note the way bone meal or blood meal does. That smell sits on the dry powder while it waits in your bag. The moment you mix it into your damp soil, the feather meal odor spreads out. Soil microbes start breaking the protein down right away. Within a day or so you stop noticing it at all, even with your nose close to the bed. The same microbes that clear the smell are the ones turning that protein into food for your plants.
Outdoors the smell is faint to begin with. Open air thins it out fast. A thin layer raked into the top few inches of your bed gives off far less than you would think. The odor gets stronger in only two spots. One is inside a sealed bag where the air has nowhere to go. The other is when the product gets damp and sits too long. Even at its peak it is nowhere near as sharp as fresh manure. You can stand right over a worked-in bed and barely catch it on a warm day. If you have ever spread composted manure, you already know feather meal is the gentler choice for your senses.
Feather meal has a mild, earthy, animal-protein note that is strongest in a sealed or damp bag. Worked into soil and watered in, it fades from the air within about a day.
Good fertilizer storage keeps the smell down before you ever spread it. Roll your bag closed and clip it shut. Better yet, pour the powder into a sealed bucket with a tight lid. Keep your bag off a damp garage floor and out of the rain. Dry feather meal barely smells at all. A bag that took on moisture and clumped is the one that turns musty on you. Damp product is also slower to feed your plants, so you lose twice when it gets wet. Store it dry and you sidestep both problems at once. I keep mine in a lidded bin on a shelf, and it stays odorless between feedings.
How you apply it matters just as much as how you store it. Work the powder into your soil rather than leaving it sitting on top. Buried product gives off almost nothing. A surface dusting is the part that can hold a faint feather meal odor for a few days. It can also draw curious dogs or raccoons in to dig at your bed. So rake the powder into the top two to three inches of your soil. Then soak the bed well. The water carries the protein down toward the root zone. That single step cuts both the smell and the pest interest at the same time, which is why I never skip it.
Do those three things and the feather meal smell stops being a question for you. Keep your bag sealed and dry. Mix the powder in instead of topdressing it. Water it in right after you spread it. I have run feather meal across that fence-line bed for years now. The only time I notice it anymore is the second the fresh bag opens. After that it is mix, water, done.
