How to Buy Hay: A Complete Guide

Buying hay is one of the most consequential purchasing decisions a small farm makes — and most people do it with less preparation than buying a used appliance. Poor hay can cost you in two ways: directly (wasted money on a load your animals won't eat) and indirectly (nutritional deficiencies, health problems, and the scramble to find replacement hay mid-winter). This guide gives you everything you need before you load the first bale.

Before You Go: Know What You're Buying For

The single biggest mistake buyers make is searching for "hay" without knowing what their specific animals need. Hay is not a commodity — a load of straight alfalfa that's perfect for a lactating dairy doe can cause urinary calculi in a wether, and a load of mature first-cutting fescue that's fine for your beef cows may be inadequate for a working horse. Before you buy, know:

• Which animals you're feeding and their life stage (dry, pregnant, lactating, growing, working)
• Whether you need a grass hay, legume hay, or a mix (see our hay types guide)
• Whether first cutting or a later cutting is appropriate for your animals (see our cutting comparison guide)
• How much you need — calculate this before you go rather than guessing (use the Winter Hay Calculator)

Finding Local Hay Sellers

The best hay sources are often not the most visible ones. The cleanest, most consistently high-quality hay typically comes from established local farms with repeat customers — not from casual Craigslist listings. Places to find hay:

• Local farm networks and co-ops: Ask at your local feed store — they usually know who the reliable hay producers are in the area.
• County extension offices: Extension agents often maintain lists of hay producers, especially in agricultural counties. Call your local extension office directly.
• Neighbor farms and word of mouth: The farmer with clean fields and neat equipment is usually the farmer with good hay. Ask who your neighboring farms buy from.
• Hay directories and local classifieds: FarmersMarketOnline, HayExchange, and local Facebook farm groups are useful starting points — but always inspect before buying.
• Auctions: Hay auctions exist in most agricultural areas. Quality is variable and you often can't inspect individual lots thoroughly. Best for experienced buyers who can assess quality quickly.

What to Inspect When You Arrive

Never buy hay you haven't inspected. The following checks take less than 10 minutes and will prevent the vast majority of bad purchases.

1. Smell It

Good hay smells fresh, clean, and slightly sweet — like dried grass or mild dried herbs. The smell tells you more about quality in 5 seconds than most visual checks. Specific smells to know:

• Musty or mildew smell: Indicates mold, either from high moisture at baling or weather damage in storage. Reject it.
• Ammonia or barnyard smell: The hay was stored near animal waste or got wet enough for significant fermentation. Reject it.
• Burning or caramel smell: The bale got hot from internal fermentation — a sign it was baled too wet. This destroys protein (heat damage) and can indicate fire risk in storage. Reject it.
• Dusty smell with no mold odor: Older hay that's dry but accumulated dust. Usually acceptable for most animals, but check for leafiness — older hay loses nutritional value. Fine for horses prone to respiratory issues only if it can be soaked.

2. Look at the Color

Break open a bale or pull apart the flakes and look at the inside color — not just the outside (which weathers regardless of quality). Good hay should be:

• Golden-green to bright green: Good. The greener, the more chlorophyll retained, which correlates with nutrition preservation.
• Golden-yellow: Acceptable for grass hay. The crop was mature or sun-cured longer before baling. Not a problem unless paired with musty smell or excessive dust.
• Dark brown or black: Reject. Indicates heat damage, mold, or severe weather damage.
• Bleached white on outside only: Normal surface weathering from sun exposure. Cut into the bale — if the inside is golden-green, it's fine.

3. Check for Leafiness

Leaves contain significantly more protein, energy, and vitamins than stems. High-quality hay has a high leaf-to-stem ratio. Shake a flake over a dark surface — excessive leaf shatter (dust of leaves falling off) indicates the hay was over-cured and has lost nutritional value. Some shattering is normal; a blizzard of loose leaves from every flake is not.

4. Check Moisture — Without a Meter

Hay baled at excessive moisture (above 18–20%) heats internally, loses protein, and can develop dangerous molds. You don't need a moisture meter to spot problems:

• Place your hand inside a bale — it should feel dry and cool, not warm or damp.
• If you can access a fresh bale that was recently cut, the stems should snap cleanly when bent, not bend without breaking (which indicates excess moisture).
• Ask the seller how many days after cutting the hay was baled — good practice is 2–4 days of field drying in good weather conditions.

5. Look for Foreign Material

Pull apart several flakes from different bales and check for:

• Weeds, especially toxic species (check your regional toxic plant list — in the eastern US, watch for buttercup, black nightshade, and tansy ragwort in hay fields)
• Wire, twine, or plastic from previous bale wrapping that got incorporated
• Dirt or manure contamination from poor field conditions at baling
• Dead animals or nesting materials (less common but serious)

Questions to Ask the Seller

A reputable hay farmer will welcome these questions and answer them directly. Vague or defensive answers to basic questions are a red flag:

• "Which cutting is this?" First, second, third — and when was it cut?
• "Was it rained on after cutting?" Rain between cutting and baling reduces quality significantly.
• "What's the bale weight?" Get an actual weight, not an estimate.
• "What's the moisture content?" A good farmer knows — or will have it tested. Anything over 20% at baling is a concern.
• "Do you have a hay test?" Established hay farms often have forage analysis results available, especially for larger sales. If they do, review the CP (crude protein) and ADF numbers against your animals' needs.
• "Was the field fertilized this year?" Unfertilized fields typically produce lower-protein hay. Important for high-demand animals.
• "Is there any fescue in the mix?" Especially important in the Southeast and Midwest — infected fescue causes problems in horses and some other livestock. Ask about endophyte status.

Pricing: What's Reasonable in 2025

Hay prices vary enormously by region, year, drought status, and hay type. Rough 2025 ranges across the US:

Always compare price per 100 lbs, not per bale. A $7 square bale at 40 lbs costs $17.50 per 100 lbs. A $9 bale at 60 lbs costs $15 per 100 lbs — it's cheaper despite the higher sticker price. For round bales, divide the price by the bale weight to get your cost per pound.

Buying in Bulk vs As-Needed

Buying a full winter's supply in summer (before or just after first cutting) typically costs 15–30% less than buying the same hay in January when supply is tight and you're negotiating from a position of urgency. The trade-off is storage — you need a dry, protected space for the full supply.

If you don't have adequate storage for a full supply, buying in smaller batches is reasonable — but keep a rolling 4–6 week supply on hand so you're never making emergency purchases in winter. The farmer who knows you'll need another load in February can charge accordingly.

Red Flags — Walk Away If:

• The seller won't let you inspect individual bales before loading
• There's a strong musty or ammonia smell from the stack
• Bales are dark brown on the outside and warm inside
• The price is significantly below local market rate (cheap hay is cheap for a reason)
• The seller doesn't know which cutting it is or how long ago it was baled
• Bales are stored directly on bare dirt with no protection and show significant bottom rot
