Education Pt. 30: Spring Set Day SOP: Receiving, Resting, and Setting Eggs (Local + Shipped)

Zero G’s exact protocol so your first set starts clean and stays clean.

Mission Brief

Spring sets are where the season gets decided. If your first eggs start sloppy—wrong storage, rushed setting, damaged air cells ignored—you’ll spend the rest of the hatch chasing problems that weren’t “incubator issues” at all. This is our Set Day SOP at Zero G Quail Farms: how we receive eggs (local or shipped), how we rest them, how we candle, and how we set them so the hatch begins with stable conditions and repeatable records.

Non-negotiable orientation (commit this to muscle memory):Hatching eggs are stored/rested/incubated upright with the large end up (air cell up), pointy end down. Always.

What You Need Ready Before Eggs Arrive

• Clean counter space and clean hands (no scented cleaners or aerosols near eggs)

• A stable room (ideally 68–75°F) where eggs can rest undisturbed

• Egg cartons or upright rails (quail rails if you’ve got them)

• Candler (or strong flashlight with a cardboard collar)

• Labels/Sharpie + log sheet (source, date received, set date, pen/lot)

• Incubator fully tested (our rule: 48–72 hour burn-in in the same room you’ll run it)

Reminder: All incubators lie until you verify. Set day is not the day to learn your machine drifts.

Step 1: Receiving Eggs (Local Pickup vs Shipped)

Local pickup

Local eggs usually arrive with fewer variables, but don’t assume “perfect.” Transport still matters. Keep eggs out of sun, don’t let them roll, and avoid leaving them in a cold vehicle.

On arrival: keep them upright, large end up, and get them into the resting area.

Shipped eggs

Shipping adds four major risks: impact, vibration, and temperature swings, and laying elevation vs your elevation. Even with a reputable breeder who test hatches, the carrier can still shake an egg’s internal structure. That doesn’t mean the breeder is the problem—it means you need a shipped-egg procedure.

On arrival: open the box indoors, keep eggs upright, large end up, and do not rush them into a warm incubator.

Step 2: Candling on Arrival (Your Triage Step)

Candling isn’t about “is it fertile?” on Day 0. It’s about air cell condition and obvious damage.

What you’re looking for

• Normal air cell: a clean, stable air pocket at the large end

• Detached air cell: air pocket floating or shifting

• Saddled air cell: air cell stretched along the side wall

• Hairline cracks: especially around the large end (Note: Pay special attention to what is a crack vs a scratch on the egg. Super bright lines indicate cracks and dull or less defined indicate scratches; Scratches are not bad, cracks are bad.)

What to do with cracked eggs

For hatching purposes, cracks are a biosecurity and failure risk. We do not recommend setting cracked eggs. If you choose to experiment, treat them as a separate test group and never mix them with clean sets.

Log your findings (especially shipped eggs). Notes now save you from guessing later.

Step 3 : Resting Eggs (This is Where Most People Rush)

Eggs need time to settle internal structures—especially after movement.

Standard rest (local or shipped)

• Rest 12–24 hours at room temperature

• Keep eggs upright, large end up

• Don’t rotate or roll them during the rest period

• Keep them away from fans, heaters, and direct sunlight

Why rest matters

Resting reduces problems tied to agitation and gives you a stable baseline before you candle and set. You’re not “wasting time.” You’re preventing preventable losses.

Step 4: Decide Your “Set Plan” (Normal vs Damaged Air Cells)

This is the fork in the road. Your setup changes based on what the candle shows.

If air cells look "normal"

Proceed with a normal incubation plan:

• Set eggs upright in your turner/rails (large end up)

  OR

• Use normal turning method for your system

If air cells are detached or saddled (common in shipped eggs)

This is where most people fail by “treating shipped eggs like local eggs.” Don’t.

Zero G shipped-egg stabilization protocol:

• Incubate upright, large end up if possible.

• For the first 2 days, do not tilt or full roll turn.

• After day 2 begin "normal" incubation process.

• IF possible try and lockdown the eggs in the same orientation of pointy end down to allow the chicks the easiest access to the air cell as possible.

This reduces internal shear forces while membranes settle and gives the highest chance for an established air cell to be formed.

Step 5: Incubator Pre-Flight (Before You Set a Single Egg)

Set day only goes well if the incubator is already proven.

Zero G pre-flight checklist

• Burn-in complete: ran 48–72 hours

• Verified at egg height: independent thermometer + hygrometer at tray level

• Turning confirmed: turner actually moves smoothly and doesn’t pinch quail eggs

• Water system tested: humidity method consistent and repeatable

• Room stable: no drafts, no sun hits, no vent blasting the incubator

If your incubator hasn’t run since last year, pre-flight isn’t optional—it's survival.

Step 6: Setting Eggs (The Actual Set Day Sequence)

1. Wash hands and prep labels/log sheet

2. Place eggs upright in rails/turner (large end up)

3. Confirm turner clearance (no egg rubbing, no pinching)

4. Close the unit and let it stabilize—don’t “peek” every 10 minutes

5. Log: set time, source, lot/pen, room temp, verified incubator readings

Your job after set: don’t manage emotions. Manage numbers.

Step 7: Week 1 Follow-Up (So You Don’t Fly Blind)

• Day 3–5: verify turning is still working and nothing shifted

• Veryify temperature and humidty is in range and no swings are occuring. (A lower temperature by half a degree is not near as negative as a several degree temp or humidity swing everyday)

• Keep notes on hatch groups—local vs shipped, line vs line. This is how you learn what works for your setup.

Common Set Day Mistakes (And the Fix)

Mistake: Setting eggs immediately after delivery.

Fix: Always rest 12–24 hours upright, large end up.

Mistake: Over handling of eggs.

Fix: Do not candle or move the eggs around after they have been set in the incubator more than necessary. Extra candling or handling will not improve your hatch or fix a bad hatch but you can negatively impact the hatch.

Mistake: Trusting incubator numbers blindly.

Fix: Verify at egg height. All incubators lie PERIOD.

Mistake: No labeling/logging.

Fix: Track source, date, and pen/lot. If it’s not written, it didn’t happen.

Zero G Bottom Line

A clean set starts long before you close the incubator door. Receive eggs calmly, rest them upright large end up, candle on arrival, and treat shipped eggs like the fragile cargo they are—especially when air cells are detached or saddled. Stabilize first, then turn. Track everything. When your first set starts clean, the rest of the season runs smoother. Systems on.

Zero G Note: WE do not recomend candling more than after the day that you receive the eggs. Candling while it is a tool is a tool that if used improperly will greatly impact your hatch in a negative way. Candling while it will show you eggs that have stopped will not cause stopped eggs to start again, but it can have a huge chance to stop an egg that was actively developing. Mistakes happen, dropping an egg, discarding an egg that looks like it has stopped development and it hasn't. WE recommend candling only once and if doing it a second time ONLY do it when setting the eggs for lockdown.
