Regardless of the number of times I have hatched chicks, the process of embryo development fascinates me equally each time. That a chicken egg can evolve from common recipe ingredient into a living, breathing, fluffy-butt in a mere 21 days fits my definition of miraculous.The following photo presentation pairs well-known images from the Purdue Research Institute, depicting embryo development from the inside, with my own photos of candled eggs throughout the 21 chicken egg incubation period. 
I invite you to view any one of my YouTube videos to witness the wonder of hatch day. Baby Chick Hatching in Home Incubator, Singing and Dancing Easter Egger, Hatch Day! Ameraucana Chick Arrives! and Hatching Easter Egger.
Egg candling was done using the Brinsea OvaScope egg candler.

I just found your blog the other day and can't thank you enough for all the posts and information!! I was wondering if you have ever encountered this… we have been trying to hatch a white egg from our flock. Only one of our chickens (a leg horn) lays white so we know who it is from. Our rooster, an Americauna, is healthy and we get the chicks to around day 18-19 and they stop moving when we candle them and die… it is just heart breaking and my girls so have their heart set on hatching a white one.… Read more »
What kind of incubator are you using? What are the temp and humidity settings on them at lockdown?
Such a miracle.

It is addicting, Sara. No question!
Awesome post!
What kind of chick is that in the last pic?
That's one of my Black Copper Marans chicks. :)
This is my first visit – and I've signed up as a follower. I have backyard chickens; our city house is for sale and we're about to move to the country. I CAN'T WAIT to experience the hatching of baby chicks! Thank you for showing and explaining in detail. Wonderful!

Hi Lana! Thanks so much for following along. You're going to love the whole incubation process. Don't say you weren't warned though! LOL
Enjoy and keep me posted on how it goes!
