Incubating chicken eggs: the journey from speck to chick in 21 days.

Incubating and hatching your own chicken eggs is an amazing experience – but if you've not done it before, it can feel quite stressful.

In these articles, I guide you through the process on all twenty-one days of the incubation cycle, week by week.

Following along, you'll know exactly what should be happening, what to do, and what you need to look out for at every stage.

How to incubate and hatch chicks. Pin for later.

Do you feel like this?

Are you excited – and at the same time terrified?

I'll let you into a secret: I was more nervous incubating chicken eggs for the first time than at almost any other time of my life. I fussed about like the proverbial mother hen, worrying about anything and everything that could go wrong. 

Occasionally, when I thought I'd done everything wrong, I cried.

If you feel a bit like that, you need to know - it doesn't have to be that way!

There are very definite patterns from the start of incubation right through to hatching time. Recognising them will help you identify whether your eggs are following the right path.

Even if you're not hatching eggs yourself, it's a fascinating journey to see.

Once you've done it you'll feel euphoric, satisfied, elated, proud – and confident enough to do it all over again. I guarantee, you'll be hooked!

So join with me here and let the journey begin!
