Development of a Chicken Embryo Day by Day

Excellent guide to day-by-day development. Thank you for taking the time and effort to create this.

Such a great post!! Super detailed and great to use to explain things to the kids as we follow our hatches

This is my third time trying to write this review.
I learned so much, I don’t know where to begin.
The pictures are incredible, and how they were edited to make it easier to see the development is amazing in itself.
Learning the correct terminology is something I appreciate.
Learning when different body parts are developing, where the waste goes, that the chic gets some air through the egg shell, just incredible!
Thank you for sharing your knowledge! I will be bookmarking this article & referring people to it.
I wish I could give it more stars!

What a great read - I am such a visual person, and this really helps when questions about development during incubation pop up for me. Thank you!

I've seen videos & pictorials, which I always find to be awesome! Thank you so much for sharing the miracle of life.

Very informative and helpful article. Lots of great photos and easy to understand information.

This is very informative, to the point, and backed with really good pictures! Thank you, I really enjoyed it

This is a great article!!!
Very informative - I am doing a hatch along and this is making things a bit clearer on when the best time is to candle light!

This is very comprehensive! It helps a lot to see day by day development!

Amazing article to read for better understanding of the development of an egg.

So much great info! I have no intention of incubating eggs but am amazed at the process nonetheless!

This is very informative. I do wish there had been some information on how/best candler etc for very dark olive, dark brown, or thicker shelled eggs. I would have loved to see examples of quitters at various stages compared to the progression.this was still one of the best i have seen on the internet..

Such a wonderfully useful article.

I just put 24 eggs into my 22 egg Nurture Right 360 and needed to know how soon I'm going to be able to see development well (I'm expecting some infertile eggs due to my rooster-to-hen ratio).

Pictures are nice and clear with information about each day. Well done!

Very clearly explained for the total novice in this field. So good to have such clear day by day pictures to compare, looking at this I think I may get 5 out of 6 on my first attempt, here's hoping.

Great descriptive. Reminds me of a science project that I did in high school. Yeah, a long time ago.

Great details and pictures. Any time I'm waiting for a clutch I come back to this article several times.

Great article. Pictures are easy to make out, good quality, very good representation of what goes on during incubation. I haven't found an article other than this one to show pictures of the embryo after day 18. Maybe I'm not looking hard enough. Anyways, this was a great article and I read it twice. The summary of what happens in every picture is very compact and keeps your attention. Great job!

Thank you for a really useful file.

This is such an informative article. Along with great photos because I know how hard it is to get a photo of the embryo.
