Every detail of the Cosari HatchGrid 30 is designed around real 21-day biological tolerances—from Day 1 setting to Day 21 zipping.
Snap-in white divider bars adjust to cradle 30 chicken, 20 duck, or 54 quail eggs, sliding smoothly every 120 minutes so embryos never stick.
Fill Channel A for Days 1–18 (55% RH) and open both A + B on Day 18 (70% RH) from outside the bottom-right yellow port without lifting the lid.
Press the dedicated candler button on the top control module to inspect Day 7 spider veins and Day 14 air cells without buying a separate flashlight.
A 42 dB laminar circulation fan and factory-calibrated sensor keep all four corners of the square chamber locked at 100.0°F with zero cold spots.
No hidden menus or extra thermometers required. The yellow backlit LCD displays live 100.0°F temperature, 55% relative humidity, your 21-day countdown, and the 120-minute turner timer—with a built-in cool-LED candler right on the top-left corner.
Space the white divider rails to match the exact diameter of your chicken, duck, or quail eggs. On Day 18 Lockdown, lift out the white frame in 10 seconds so hatching chicks step straight onto the high-traction gray triangular grid.
Opening an incubator lid during Days 18–21 vents warm moisture and shrink-wraps chicks inside the membrane. Our yellow A/B corner port lets you top off both humidity channels from the outside while the chamber stays 100% sealed.

Engineered for Higher Hatch Rates: The Cosari HatchGrid 30 pairs a non-porous matte light-gray ABS bottom tub with a crystal-clear panoramic polycarbonate lid, giving you 360-degree visibility and ±0.3°F temperature stability across all 30 egg positions.
Effortless Day 18 Lockdown & Splayed-Leg Prevention: When the day counter reaches Day 18, simply lift out the white sliding divider rails and open both external A and B water ports. Newly hatched chicks stand securely on the textured gray triangular-grid floor with zero slipping.
3-Minute Post-Hatch Sanitization: Unlike porous Styrofoam incubators that absorb bacteria and smell after one cycle, the hard-shell ABS base, gray hatching grid, and white dividers wash completely clean in warm soapy water in minutes.

Farm-store Styrofoam boxes trap blood rings, dander, and bacteria inside foam pores forever. Our injection-molded matte light-gray ABS tub wipes 100% clean and odor-free in the kitchen sink.
Smooth plastic grates cause wet newly hatched chicks to slip and develop permanent splayed legs. Our precision-molded gray triangular mesh gives tiny toes instant grip from their very first step.
Compact on a kitchen counter yet spacious inside, the optical-clear lid with its ergonomic left-side handle lets the whole family or classroom watch every pip and zip without disturbing the chamber.

Snap the white divider rails into the matte light-gray base to match the width of your chicken, duck, or quail eggs and set your fertile batch.
Close the clear lid via its left handle, plug in the top controller (`100.0°F / 55%`), and fill external yellow Channel A for Days 1–18.
On Day 18, lift out the white divider rails, fill both A and B external water ports, and watch your chicks hatch on the nonslip gray mesh floor.
Upgraded from an old Styrofoam Farm Innovator after one too many messy hatches. The hard gray base and removable white tray wipe down completely, even around the corners. I can actually sanitize everything without stains and shell bits lingering.
The top heater keeps every row remarkably even, including the eggs near the corners. I get the same all-around visibility as a round 360 model, but the square clear lid and divided tray fit more eggs neatly on my utility-room counter.
The sliding tray handled turning automatically, and I added water through the yellow A/B corner port without lifting the lid. The display stayed around 100.0F and 55% humidity. We had a strong first hatch without spending a fortune.
I had no clue how to identify fertile eggs. On Day 7, I used the circular LED candler recessed into the top-left control panel and could clearly see veins. I removed the clear eggs without needing to buy another flashlight.
I always verify incubators with two Govee sensors placed inside the white tray. This one was within 0.3°F and 2% humidity right out of the box. That is better than several pricier units I have used.
When the countdown reached Day 18, I lifted out the white sliding dividers in under a minute. The chicks hatched directly onto the gray triangular-grid grate, which gave them solid footing. No slipping or splayed legs in this batch.
The yellow-capped A/B refill port and clear feed tube work exactly as hoped. I used Channel A for Days 1–18, then filled both A and B for lockdown. Humidity stayed rock steady without opening the clear lid or dumping heat.
The white dividers snap into spaced rows and hold my bantam, quail, chicken, and larger duck eggs without loose rolling. It fits about 30 regular chicken eggs. I also like seeing the 120-minute turning countdown on the yellow screen.
My third graders could gather around the glossy square lid and watch chicks pip and zip from every side. The left handle made moving it easy, and I adjusted the yellow air vents myself so little hands stayed away from the controller.
The yellow LCD shows everything at a glance: 100.0F, 55% humidity, 21 incubation days, and the 120-minute turn countdown. Between that and the five tactile front buttons, I no longer have to track batch timing on paper.

It holds up to 30 standard chicken eggs right out of the box. Because the white divided egg tray uses snap-in adjustable rails rather than fixed holes, you can space the rows wider for 20 large duck eggs or narrower for 48–54 bantam or quail eggs without buying any extra accessories.
On the bottom-right corner of the matte light-gray base is a yellow-capped external water port marked A and B. For Days 1–18, you add warm water only into Channel A using the included squeeze bottle to hold ~50–55% humidity. On Day 18 Lockdown, you fill both Channel A and Channel B from the outside to raise humidity to 65–75% without ever opening the lid.
On Day 18, simply lift the clear lid by its molded left-side handle, unclip and lift out the white adjustable divider frame (takes about 10 seconds), and place your eggs directly onto the textured gray triangular-grid hatching floor. The nonslip mesh prevents newly hatched chicks from slipping or developing splayed legs.
The top-mounted yellow backlit LCD displays temperature in crisp Fahrenheit (`100.0°F` factory preset) right alongside live relative humidity (`55%`), the automatic incubation day counter (`21`), and the 120-minute automatic turner countdown timer.
Yes. A recessed cool-LED candler is built directly into the top-left corner of the black-and-gray control module with its own dedicated button. In a dimly lit room, you simply hold an egg over the LED ring at Day 7 and Day 14 to spot fertile spider veins and air-cell development.
A full chicken incubation cycle takes 21 days from setting the eggs to hatch day. Our 30-Day Guarantee gives you a complete 21-day hatch cycle plus 9 extra days to evaluate temperature stability, auto-turning, and sink cleanup completely risk-free, backed by a 2-Year Warranty.
