Why Your Eggs Aren't Hatching: 7 Common Mistakes
A disappointing hatch is frustrating, but it's rarely a mystery once you check the usual suspects. Here are the seven issues that account for most low-hatch-rate calls we get.
1. Egg storage before incubation
Eggs held too long, at the wrong temperature, before you even start incubating will hatch poorly no matter how good the machine is. Store eggs pointed-end down, at 13–16°C, and set within 7 days for best results.
2. Temperature drift
Even a degree or two off, held for hours, can matter. Check your incubator's thermometer against a second, independent thermometer — don't trust a single reading.
3. Humidity mismanagement
Too dry and chicks stick to the shell membrane; too wet and they drown inside the shell. Humidity needs also change in the final days before hatch — check your specific model's schedule.
4. Inconsistent turning
Eggs need turning multiple times a day until lockdown. A fully automatic incubator removes this risk entirely — it's one of the most common causes of failed hatches in manually-turned setups.
5. Opening the incubator too often
Every open door drops temperature and humidity. Resist the urge to check constantly, especially in the final 3 days (lockdown), when the incubator should stay closed except for emergencies.
6. Poor egg fertility going in
No incubator can hatch an infertile egg. If your hatch rate is consistently low across multiple batches, the issue may be upstream — with the breeding flock, not the machine.
7. Skipping candling
Candling at day 7 and day 14 lets you remove clearly infertile or non-developing eggs early, rather than discovering the problem only at hatch day.
The pattern
Most of these come down to consistency — and that's exactly what a fully automatic incubator with dual power is designed to remove as a variable. If you're troubleshooting a specific batch, with your model and what you're seeing — we can usually narrow it down quickly.
