I read a thread here on BYC of a double yolker hatching two chicks, so why not?

 

[frenchblackcopper]

Please find that thread KsKingBee,,,and I wonder if the hatch was filmed?

I asked DW about it, it seems like it was a year ago or more and there were photos of the assisted hatch. I have no idea how to find it now, sorry.

Is this it? https://www.backyardchickens.com/t/104245/double-yolker-yolk-hatched-video-p-16-13-week-pics-p-51
Looks like it was in 2008.

Even if that is not the exact topic, they do have a video of them assisting both chicks out of the egg. Here is the video link:

Evidently one ended up being a rooster and the other ended up being a hen. Very interesting stuff I had no idea both chicks could survive! I am sure you would have to help them out like what they did in the video.

I wonder if you hatched 2 pied chicks from the same egg if they would have identical markings?

 

[KsKingBee]

Interesting thought Minx, no I don't think they would be identical as they are two separate eggs in the same'womb' not an egg that divided.

You know in cattle if a cow has twins with one being a male (bull) and the other being a female (heifer) the female calf is sterile? Caused by the testerone levels going up as the male calf grows? Wonder if the hen chick could produce eggs that was fertile? Forgot to add they are called "freemartins"

Is this also true with horses, goats and sheep? Just curious...

Kathy,,this I do not know. I think (without internet searching a lot) in cows this is caused by both calves sharing the same placenta. Of course sometimes the egg splits giving you identical same sex twins and in other animals that are capable of having multiple births from one breeding,each individual must be in it;s own placenta. Such as puppies,rabbits,ect. So in animals that releases many eggs to be fertilized during their estrus cycle each fertilized egg would then have it's own placenta to grow in by itself.

In cattle with calves being the opposite sex and sharing the placenta all nutrients from the mom is shared between both calves just as everything each calf has, gets passed between them both from the umbilical cord. As the bull calf starts producing testerone it moves into the heifer twin calf and because the levels are high enough it renders her unable to reproduce. Once again a simple search of "freemartin" should explain exactly how this works but heifer calves born in twin situations where the other calf was a bull are fed out and slaughtered.
