Hatching chicken eggs at home is exciting, educational, and sometimes a bit nerve-wracking — especially if it’s your first go. Incubators can be brilliant tools, but they’re not magic boxes, and it’s really important to start with realistic expectations.
Even in good conditions, home incubators often hatch around 35–50% of eggs. That’s normal. If your eggs were posted, handled roughly, or from young or older birds, the hatch rate may be lower. That doesn’t mean you’ve failed — it means you’re hatching eggs, not operating a commercial hatchery.
With that in mind, here are my top 5 welfare-first, experience-based tips to give your eggs the best possible chance.
1. Start With Eggs That Are Properly Rested and Marked
If your eggs have been posted, this step really matters.
Always rest eggs fat end up for at least 12 hours before they go anywhere near the incubator. This allows the air cell to settle after transit. Skipping this step is one of the most common reasons early embryos fail.
Before setting:
Check for cracks or leaking
Mark each egg with a non-toxic marker pen (not pencil — it rubs off)
Use simple marks like an X and O if you’re turning by hand and mark the breed and date you put in the incubator.
Remember: egg colour doesn’t affect hatch success, and it doesn’t guarantee future egg colour unless the birds are true pure breeds.
2. Trust a Separate Temperature Probe — Not the Incubator Display
This is the single most important piece of kit you can own.
Many incubator displays are inaccurate — sometimes by enough to stop development altogether. For chicken eggs, your target is:
37.5°C
40–50% humidity for days 1–18
I always recommend using a separate temperature probe and hygrometer (available on Amazon) placed at egg level. It’s far more reliable than the built-in screen and removes a huge amount of guesswork.
A steady, correct temperature is far more important than obsessively adjusting humidity every five minutes.
3. Candle Sensibly — and Remove Non-Viable Eggs
Candling isn’t just exciting; it’s a hygiene and safety step too.
Candle your eggs around day 8–11 using a proper egg candler (you can get this on Amazon). At this stage you should see:
Veins and movement in fertile eggs
Clear eggs (infertile)
Early “quitters” where development has stopped
Remove any eggs that aren’t developing. Leaving them in risks bacterial growth, which can harm healthy embryos nearby.
After handling eggs or trays, clean properly — an incubator-safe cleaner (Amazon link) helps reduce bacteria between hatches.
4. Prepare Properly for Hatch Day (Lockdown Matters)
Day 18 is a big turning point.
On day 18:
Stop turning the eggs
Increase humidity slightly (usually to around 65%)
Add a non-slip liner to the incubator floor (find it on Amazon)
That liner is vital. Without it, chicks can slip, which can lead to splayed legs — a preventable welfare issue.
Once pipping starts, do not open the incubator. Even a quick peek can cause the membrane to dry out and trap the chick. Hatching can take 24–48 hours, and that’s completely normal.
5. Leave Chicks Until They’re Fully Dry (No Rushing)
Newly hatched chicks don’t need food or water straight away — they’re living off the absorbed yolk.
Leave chicks in the incubator until they are:
Fully dry
Fluffed up
Standing confidently
This can take up to 48 hours, and that’s fine. Moving them too early can chill them and undo all your careful work.
When they do move to the brooder, make sure it’s fully warmed and ready before hatch day arrives.
A Gentle Reality Check (and Reassurance)
Not all eggs hatch. Some chicks won’t make it to zip-up. That’s emotionally hard — especially with children watching — but it’s a normal part of hatching and not a reflection of how much you cared.
Each hatch teaches you something, and even a small number of healthy chicks is a success.
If you approach incubation calmly, with good equipment, steady conditions, and realistic expectations, you’re already doing right by your birds.
Pop the kettle on, keep notes, and remember — you’re learning a skill humans have been practising for centuries. 🐣
