What Should You Actually Write Down During a Hatch?

Quick answer: Write down the things you will actually wish you had later: set date, batch ID, egg count, candling results, lockdown date, hatch totals, losses, and any unusual changes. If it would help explain a good hatch or a bad one a week from now, it is worth recording.

If you are wondering what you should actually write down during a hatch, the short answer is this: not everything, but definitely more than most of us remember in the moment. I learned pretty quickly that memory is excellent at sounding confident and terrible at keeping batches straight once you have enough eggs going.

And yes, I have absolutely stood next to an incubator thinking, “I know I wrote that down somewhere,” like that was going to help.

The real goal is not note-taking for its own sake

I am not trying to turn hatch day into office work.

The point of keeping records is simple. When a hatch goes well, I want to know what was normal. When a hatch goes sideways, I want some kind of trail to follow besides shrugging and blaming the moon.

Good hatch notes should help you answer a few basic questions later:

• What batch was this?
• When did key milestones happen?
• What changed along the way?
• How many chicks actually hatched?
• Was there anything unusual that might explain the result?

If your notes can answer those questions, you are in pretty good shape.

What I would write down every single time

If you want the practical version, here is the core list I think matters most.

1. Batch ID or some kind of clear label

Every batch needs a name, code, or label that is easy to recognize.

It does not have to be fancy. It just has to be clear enough that you are not guessing later whether “the eggs from the blue tote” were this set or last week's set.

I have learned this the dumb way. Once you have multiple incubators, staggered set dates, or different breeds going at once, vague labels become farm-flavored chaos.

2. Set date

This is the anchor for everything else.

If the set date is wrong, every milestone after that starts drifting too. Candling checks, lockdown, expected hatch, all of it.

I know that sounds obvious, but obvious things are exactly what get skipped when you are busy.

3. Species or breed

Write down what the batch actually is.

That matters because incubation length, expectations, and hatch timing can vary. A chicken batch is one thing. Pheasants or other birds can be another.

You do not want to be halfway through troubleshooting and realize you never clearly wrote down what you were comparing.

4. Starting egg count

How many eggs went in?

That one number gives context to everything that follows. Without it, hatch totals are a lot less meaningful.

Ten chicks out of twelve eggs feels very different than ten chicks out of thirty.

5. Incubator or location

If you have more than one incubator, cabinet, shelf, room, or tray, record where the batch is.

This matters more than people think. If one incubator runs a little dry, one tray runs warmer, or one shelf keeps giving you weird results, you need a way to see that pattern.

This is one of those places where my software-brain kicks in. If a problem keeps happening in the same place, that is not bad luck anymore. That is a clue.

What to record during incubation

Once the eggs are set, I do not think you need to write a novel. I do think you need to capture the checkpoints that actually affect decisions.

6. Candling dates and quick results

When did you candle, and what did you see?

That can be as simple as:

• day 7, mostly good veining
• removed 3 clears
• one questionable egg left in for recheck

That is enough.

You do not need a dramatic write-up like you are narrating a wildlife documentary. Just record what helps future-you understand what changed.

For more on timing those checks, see when to candle eggs and what you’re looking for.

7. Any egg removals or losses before hatch

If you remove clears, quitters, cracked eggs, or anything suspicious, write that down.

Otherwise your final hatch numbers get fuzzy fast.

It also helps you separate fertility issues from hatch issues, which are not the same problem even though they can look the same when the recordkeeping is sloppy.

8. Unusual events or changes

This is where short notes really earn their keep.

If something weird happens, write it down:

• power flicker
• humidity dropped lower than normal
• moved batch to a different cabinet
• turner stopped for a while
• room temperature was all over the place

You are not trying to log every breath the incubator takes. You are capturing the moments that might explain the outcome later.

What to write down at lockdown

Lockdown is the final stretch before hatch when you stop turning the eggs and shift into hatch setup.

This is one of the most useful milestones to record because it changes how you handle the batch.

At minimum, I would log:

• lockdown date
• whether eggs were moved out of the turner
• any setup changes for hatch
• anything unusual right before hatch

If you want the full breakdown of that stage, what changes at lockdown covers it in more detail.

What to write down on hatch day

This is the part people often mean when they ask what to write down during a hatch.

Here is what I care about most.

9. First pip or first signs of hatch

You do not have to obsess over the exact minute unless you enjoy that sort of stress hobby.

But it is useful to note when the batch really starts moving, especially if you are comparing one hatch to another later.

10. Number hatched

This is the big one.

Write down how many chicks actually hatch, and ideally update it once the hatch is clearly finished.

A vague “looked decent” is not a number. Ask me how I know.

11. Number of unhatched eggs or obvious losses

Again, this helps separate a strong hatch from a disappointing one in a way that is actually measurable.

If you do any follow-up checks on unhatched eggs, note the basic result. Nothing fancy. Just enough to understand whether the issue looked early, mid-stage, or late.

12. Anything weird about the hatch itself

This can include things like:

• hatch ran later than expected
• several weak chicks
• one incubator area hatched earlier than another
• sticky hatch concerns
• one tray had much poorer results than the rest

These notes may seem small in the moment. Later, they are often the difference between “I have no idea what happened” and “I think I know where to look first.”

The list I would keep taped nearby

If I wanted the simplest possible checklist near the incubator, it would be this:

1. Batch label
2. Set date
3. Species or breed
4. Starting egg count
5. Incubator or tray location
6. Candling dates and results
7. Eggs removed or losses before hatch
8. Lockdown date
9. Hatch totals
10. Unhatched eggs or losses
11. Notes on anything unusual

That is enough to be useful without turning you into a full-time hatch secretary.

What I would not bother writing down

Not every detail deserves a permanent record.

I usually would not bother logging every tiny routine action if nothing meaningful changed. If the incubator was stable, the schedule was normal, and the batch stayed on track, I am fine with short records.

The trick is writing down the details that explain outcomes, not collecting data just to feel productive.

There is a big difference between useful records and decorative paperwork.

Why I built EasyIncubate around this idea

This is one of the big reasons I built EasyIncubate.

I did not want hatch records to live in random notebooks, text messages to myself, or whatever scrap of cardboard happened to be nearby at the time. I wanted one clear record per batch, with milestones and notes that still made sense later.

Because once you start juggling more than one hatch, “I am pretty sure I remember” becomes a terrible management strategy.

That may work for where you left your coffee. It is not great for tracking hatch performance.

To conclude

If you are trying to decide what you should actually write down during a hatch, keep it practical. Record the batch, the timeline, the checkpoints, the outcome, and anything unusual that could explain the result later.

That is the sweet spot. Enough information to learn from the hatch, not so much that recordkeeping becomes its own separate hobby.

If you want a cleaner way to track batches, candling, lockdown, hatch totals, and notes in one place, start your trial and see if EasyIncubate fits the way you work.
