Best hay for outdoor rabbits in damp weather

Keeping a rabbit in an outdoor hutch adds a real variable that indoor owners never have to think about: moisture. Damp hay goes mouldy fast, and mouldy hay is genuinely dangerous — it causes respiratory problems and digestive upset. Before we get into that, the foundation still applies regardless of where your rabbit lives: hay should make up around 80% of the diet. It's not a supplement, it's the core — it keeps the gut moving and continuously wears down teeth that never stop growing. Pellets should be a small daily measure, not the main event. Now — tell me about your rabbit. How old is he or she, are they healthy, and what are you currently feeding?

Good — a 4-year-old Silver Fox at healthy weight on Excel pellets with hay is a solid baseline. The damp issue you're describing is the most common problem outdoor rabbit owners hit, and it's worth solving properly because musty or mouldy hay being nibbled on all day is a real risk. The local meadow hay is a nice idea but loose farm hay is usually the worst offender in wet weather — it tends to arrive with variable moisture content already, and it clumps. Can I ask: how is the hay stored inside the hutch — loose in a rack, in a box, just scattered on the floor?

That angled rain problem is really common with wall-mounted racks — there's no great solution on the hutch side short of a proper weatherproof cover. But the hay itself can make a big difference. My recommendation is Burgess Excel Timothy Hay. Timothy hay is cut and dried to a consistently low moisture level — much more controlled than typical meadow hay from a farm — which means it starts drier and takes longer to become problematic when the air is damp. Burgess Excel pack it in resealable bags, which matters for outdoor storage, and the stems are firm enough that air circulates through the rack rather than the hay compacting into a damp mat. It's also nutritionally very good for an adult rabbit — high fibre, appropriate for her age and size. A Silver Fox is a medium-to-large breed, so you'll want to use the larger bag size to make sure she's getting unlimited access without you running out mid-week.

Honestly, rabbits don't need a winter dietary supplement the way some animals do. The main outdoor winter concern is calories — rabbits in cold environments do burn slightly more energy staying warm — but if she's a healthy weight on unlimited hay plus a measured portion of Excel pellets, she's covered. What matters more is making sure the hay is always available and dry so she can eat the volume she needs. If you want to add variety, a handful of fresh leafy greens daily is worthwhile year-round — things like romaine, spring greens, or fresh herbs. But don't add extra pellets thinking she needs more in winter; that's how weight problems start. Keep the hay flowing freely, switch to the Timothy, and sort that cover if you can.

You'll likely notice the difference quite quickly — it's a cleaner, more consistent product than loose farm hay. Buy in the larger bags, store them somewhere dry indoors, and only put a few days' worth in the hutch rack at a time. That way even if some gets a bit damp, you're refreshing it regularly rather than leaving a deteriorating supply sitting there. Your Silver Fox sounds well looked after — this is just tightening up the one weak point.
