This is really cool. We have had chickens for 1.5 years now and they are wonderful creatures, and the eggs you can produce yourself are just so much better and more nutritious than you get from the grocery store. Makes us want to share the love: next month 150 chickens will arrive to our farm and we start selling eggs to friends and neighbours. Need to watch the other videos of the channel to get a deep dive to the inner workings of poultry.
What I found surprising is that there's only a 15 minute window (in the infindibulum) where fertilization can occur. But the chicken still goes through all the steps of forming a complete egg even if no fertilization happens, which seems like a pretty likely outcome if the window is so short. That seems surprisingly wasteful from an evolutionary perspective. Is this due to humans breeding chickens to be more reliable egg layers, or is there some other reason I don't understand? Maybe in the wild, successful fertilization is more of a sure thing than it sounds?
Biology is so cool.<p>Every place you look there are these amazing processes going on. It's not just in rare or special situations like hydrothermal vents. Chickens have rifled uteruses, your body produces 1-10 billion of a certain cell per kg per day (neutrophils) that not only generate bleach to kill bacteria[0] but also sometimes just explode the DNA out of their own nuclei to trap pathogens[1].<p>0: <a href="https://en.wikipedia.org/wiki/Hypochlorous_acid" rel="nofollow">https://en.wikipedia.org/wiki/Hypochlorous_acid</a>

What a great informative video!<p>From experience the long tube is very distinguishable from the rest of the internals as it's surprisingly large in diameter (larger than any guts), thick and white.<p>Also the unborn yolks can be cooked just like a regular egg yellow and has exactly the same taste/texture.
Man the internet (and capitalism) is amazing. Thanks for sharing.<p>EDIT: Also evolution is fucking amazing. Check out the bit around 4:40 about this thing called the "chalazae".
