Can You Hatch ONLY Hens?

Is it possible to only hatch hens? We tried hatching more hens than roosters by testing three variables: by setting only round eggs, by storing hatching eggs at 40*F for 8 hours, and by maintaining an incubation temperature .5*F less than the standard recommendation. We ended up with 16 healthy chicks! The mixed breeds of these chicks make it more difficult to determine gender until they reach maturity, and you can see each chick at 1 day old and 1 week old. We’ll tell you about some characteristics of each mixed breed that help identify their gender and show you our best guess for each chick. Follow them in their journey to adulthood to see if our experimental variables helped us hatch more hens than roosters!

If you said the sex is already determined when you're holding the egg (before incubation), then why would changing the temps matter?

Looks like this video is now 9 months old. I can't find the results video. Would love to know how this turned out.

Why do ppl call a male a roo? It sounds silly. Cockarel, cock "male" pullet, hen "female" when did a kangaroo have anything to do with a chicken?

[amymartin]

Was #5 a roo? Great video. I was smiling while watching.

I'm interested in the results, thanks for making this !

Well, I chose only round eggs to hatch out. 12 round eggs equaled 9 roosters!!!

Hello, would you say the hen were lighter and smaller with this method?

[reneebrown]

In quail you can easily get only roos or hens by adjusting the incubator temperature. Cooler gets hens hotter gets roos.

I been hatching with my egg incubator with chicks, I got to many roosters is 18, and I got the 4 hens that’s all, when I was think about it, to try the loss weights is 54g or 56g with eggs hens, but I know is different is long point that is rooster, so we just keep learning to find out, and figure that out?

I tried the round egg theory. I incubated sex links so I could tell right away. I got 2 roosters and 7 hens out of 10 eggs. I’m trying again to see if the theory holds. The hen determines the sex so maybe my 6 Barred Rocks just spit out hens. This time I added 3 Cream Legbars/Dominique crosses.

I used the round egg method last year and out of 10 eggs we hatched 2 hens and 8 roosters. I am anxious to see how you do. Good luck😃

The other issue I would like to state is that the breeds you are brooding are more prone to cross beak than the majority of breeds so you may be setting yourself up for either alot of extra care or possibly having to euthanize.

How do you get a kangaroo out of the egg?

[brendachilders]

40 is too cold to store the eggs, and this is nuts… i doubt she hatched mauch… killing baby eggs, shame shame…

[jamaeldudley]

Are there baby chicks inside?*kisses egg* Salmonella be damned! Lol

[lithod]

@2:02 1099 degrees??? What? That is a really fried hard egg!

[jamesdiamond]

Alligators and crocodiles hatch male or females depending on the temperature of the incubation

[adaywithaleks]

The round egg theory is also something certain peopoe believe in Russia interesting enough.

[Rockygameyard]

What legband are you using for the baby chicks

[jaynakonecny]

Please update very interested in your results!
