Candling Day 9, twins?

[Doctamomma]

We were candling to mark air cells and came across this in an average sized egg. Looks like two chicks? Anyone else see this before ? The egg is not big like a double yolker would be in this chicken.

So today is day 16 and the twins are still doing great I'm Hoping for the best

Have you seen the YouTube video on the twin egg hatching? Please prepare yourself that 95% of the time they do not survive. But, as that video shows, sometimes miracles happen! Hoping the best for them!

Thanks for the suggestion. We have watched the video several times. We lock down tomorrow and from what I have read it is not likely they will survive even with assistance. At this point I am happy to see movement, but it is hard to tell if it is one or both moving? It is not a big egg either, did not look like a double yolked egg, so there may not be enough nutrition to make until hatch day. Still surprised that we saw two in there... This is our second time hatching eggs, our first hatch rate was 80 percent. We have 17 left after I removed the ones that stopped developing or were infertile at day 10 and Sunday is day 21.

I'll keep an eye out for you on Sunday! Last month there was a BYC member that had one and she was very excited. She saw movement at lockdown. I was routing for that egg. It rocked and rolled on hatch day but died. When she opened the egg after it didnt hatch, she was disturbed by what she found. One semi formed chick but the other one was growing into it and sharing organs, I believe. All deformed. She was upset. I felt bad because I was excited for that egg. That's why I said to be prepared. Once you start incubating an egg and then find a double yoke developing, all you can do is pray for the best, right!!

I used to have twin roosters that hatched from a single yolk egg. I didn't hatch them, but got them from a breeder who said that's what happened. They were literally identical, until they grew up when one was bigger. Not sure how they hatched, but they did!
Good luck on Sunday, I'll be checking the thread for updates!
Here's my twins! Corny (Left) and Calder (Right) That's half of their half brother in the back, lol

Twin chicks, when successful, do not come from a single yolk, rather from a double-yolked egg. While similar, I would not consider these birds identical (not just referring to size) - but that would be expected from any birds of the same breed as the similarity in appearance can be quite striking.

Well, that's just what their breeder said...I did incubate one egg one time that had two embryos attached to the same yolk. They were both alive and moving, but didn't make it past week two.
As for being identical, Corny and Cal looked exactly the same growing up, and with most of my chickens I can tell them apart...this pic is after Calder starter going downhill with his health. He lost most of the black gold laced roos have on their chests (Not sure why) and his wattles practically disappeared. He eventually died, and Corny mourned for WEEKS. He wouldn't leave the coop, he wouldn't crow, I had to stay with him and make sure he ate. They were very attached, needless to say. Corny's still around, but never did get quite as vigorous as he used to be.
So, weather it was a double or single yolk egg I'll never know for sure, but they were both definitely a lot smaller than other Polish when I got them at two days old.

They are beautiful roosters. Neat to hear of twins surviving.

Just as in human development, when identical twins share the same placenta, while fraternal twins each have their own placenta... chicks would be identical if they shared the same yolk, and fraternal if they each had a yolk.
