Eggy Care

Controlling incubation environment is the only thing that matters

I spent three years running small-scale chicken incubation before I stopped losing hatches to minor fluctuations. The core concept here is straightforward: eggs need a very narrow band of temperature and humidity, plus regular turning, from day one until pip. Anything outside those bands and you start getting early deaths, malpositions, or weak chicks. The equipment available now makes this significantly easier than it was five or six years ago. Eggy Care is a software platform and mobile app ecosystem designed to manage and automate the incubation process. It connects to hardware controllers — primarily those from Brinsea and some DIY Arduino-based setups — to monitor temperature, humidity, and turning cycles. The app logs data, sends alerts, and lets you input the species-specific parameters for whatever eggs you're incubating. You can switch between chicken, quail, duck, or pheasant profiles and the system adjusts the target ranges accordingly. It doesn't incubate the eggs itself. You still need a physical incubator. Eggy Care sits on top of that hardware as the brain, replacing manual thermometer checks and manual turning schedules with continuous automated monitoring. The data logging alone is worth it — I keep records going back eighteen months and I can look up exactly what happened during a bad hatch and see that the humidity dropped to thirty percent for six hours because a fan relay stuck open.

The hardware side typically uses either a dedicated controller board or a Wi-Fi enabled module that interfaces with your incubator's heating element, humidifier, and turner motor. Setup takes about twenty minutes if you're familiar with basic electrical connections. The app walks you through calibration, sensor placement, and network setup. Most people finish in under an hour. I ran into a specific problem last spring that took me two days to diagnose. My Brinsea Octave Advance unit was reporting normal temperature readings throughout the incubation cycle, but the hatch rate came out at forty-two percent instead of the usual seventy-eight percent I was getting. The Eggy Care logs showed the temperature never deviated more than half a degree, so I assumed the machine was fine. I opened up the controller and found that the thermistor was mounted directly above the heating coil rather than in the main air mass. The coil was cycling on and off, the sensor was picking up radiant heat spikes, and the controller was compensating by underheating the actual chamber. The eggs were sitting in air that was roughly 0.8 degrees F below target for the entire third week. This is the kind of thing you never catch without continuous data logging, because a handheld thermometer taken once a day would show nothing wrong. The fix was relocating the thermistor into the central airflow path using a short length of copper tubing and silicone, then recalibrating the offset in the Eggy Care settings. I also added a secondary independent thermometer as a cross-reference. Hatch rates went back to normal the next cycle.

How to set up the system properly

Start by reading the manual for your specific incubator model even if you think you already know how it works. The integration between Eggy Care and different hardware varies enough that assumptions cause problems. Make sure the humidity sensor is positioned away from direct water contact. Capacitive humidity sensors degrade quickly if water droplets hit the sensing element directly. I use a fabric wick routing system where the sensor reads ambient humidity rather than sitting in the tray water, and that's been more stable over months of use. Calibration is not optional. Factory-calibrated sensors drift, especially in the humidity range. Buy a reference hygrometer — a Vivotek or a simple analog psychrometer costs about fifteen dollars — and compare readings at day three and day twenty-one of an empty cycle. If your Eggy Care humidity reads four percent high, enter the correction factor into the calibration menu. Do the same for temperature using a known-good thermometer placed at egg level. Network connectivity is where most people hit friction. The controllers use 2.4 GHz Wi-Fi only. They will not connect to 5 GHz networks. If your router bands are combined, you may need to split them temporarily during setup. I've also had issues with routers that broadcast SSIDs with special characters in the name. The controllers choke on those. Keep the network name alphanumeric during the pairing process.

Turning frequency matters more than most guides admit. The default setting in Eggy Care for chickens is six turns per day. That works, but six to eight is the sweet spot based on the literature. Fewer turns and the embryo adheres to the membrane. More than eight and you risk disrupting development without adding benefit. For quail and smaller eggs, seven turns is adequate. Ducks and geese need slightly higher humidity — sixty percent at set versus fifty for chickens — and the Eggy Care profiles account for this but you should verify the humidifier output is sufficient for your ambient conditions. In dry climates, a standard fogger pad might not keep up. Data export is one feature people overlook until they need it. Eggy Care lets you download CSV logs directly from the app. I run monthly reports through a simple spreadsheet that calculates the percentage of time the temperature stayed within the target band and flags any humidity excursions above twenty percent deviation. This takes about five minutes per month and has saved me from repeating mistakes at least twice.

Limitations and when Eggy Care won't help

The system is only as reliable as the hardware it controls. If your incubator's heating element is undersized for the room temperature, no amount of software monitoring will prevent cold snaps. I had a situation where the ambient temperature in my garage dropped to twenty-eight degrees F during a winter freeze and my 12-volt incubator couldn't maintain three inside despite the controller calling for maximum heat output. The egg deaths started on day fourteen. Upgrading to a larger incubator with a higher-wattage heating element solved it, but the lesson was that your hardware must have adequate thermal capacity for your environment. Another failure mode is sensor degradation. I replaced my humidity sensor after eleven months because the readings started lagging by ten to fifteen minutes. The actual humidity in the chamber had already changed and the sensor was responding slowly. Replacing it with a DHT22 or SHT31 grade sensor improved response time significantly. Budget sensors from unknown manufacturers often use inferior elements that degrade in six to eight months. Spend the extra money on quality sensors. Eggy Care also does not handle power outages gracefully unless you have a UPS. I lost an entire quail batch during a three-hour outage because the controller lost its memory and rebooted to default settings. A simple twelve-volt UPS rated for at least five amps keeps the controller alive long enough for the incubator's thermal mass to sustain temperatures through brief interruptions. For longer outages, you're out of luck regardless of the software.

The mobile app itself has occasional sync delays. If your phone loses connection to the controller, the app caches data locally and uploads when reconnected, but the live dashboard will show stale readings during the gap. This isn't dangerous if your hardware is functioning independently, but it means you can't rely on the app as your only monitoring source. Keep a standalone thermometer and hygrometer in the incubator as a backup. If you're attempting to incubate species that require very precise humidity swings during the lockdown period — such as certain game birds or waterfowl with specific pip timing requirements — the current Eggy Care firmware doesn't support dynamic humidity profiles that change automatically on specific days. You'd need to adjust manually or wait for a future update. This is a genuine gap for advanced breeders working with specialist species.
