Just Found 4 Legged 3 Winged Dead Chick In Incubating Egg

    [​IMG][​IMG][​IMG][​IMG][​IMG]I have been incubating eggs for years and have never found anything like this before and am wondering if anyone else has? The chick was supposed to hatch yesterday. It was a brown egg--either from a Black Sex link, Comet, or Barred Rock hen and the rooster (only one I have) was an Ameracauna. Since all other eggs hatched a day earlier than they were supposed to I decided that this one was probably dead and I was going to open it up to see what had happened to it. I was incubating 42 eggs and had 35 healthy chicks hatch.
    What a surprise to see that although it was dead, it had 4 legs, 3 wings, 2 backs and 2 cloacas, one visible head but I think judging by the size of the neck it might have had extra tissue there. It looks like it had a blister on the top of its head too. Its abdomen was wide open and the yolk was rather large and still attached. I have pictures but they are kind of graphic and I don't want to offend anyone.
    I wonder how this happened? There was only one yolk in there!

    On closer inspection I found the chick actually had 4 wings and 4 legs, the neck kind of felt bulbous like it might have had some extra tissue in it--maybe a 2nd brain?

    Ok. I just posted some of the pictures but they went into the original post above. I will try to send a video of the chick which will help explain its anatomy better.

    I am new to posting but will send some pictures. I will try to put a video in it too. First I just have to figure out how to do this.

    I would love to see the pictures however it is done. I am fairly new to byc but I think you can respond privately??

    Sounds like early in development the embryo split incompletely, it would have made 'identical' twins had there been room to fully separate. Can you photo-bucket the pictures and post or PM me a link? people that don't want to see can just not look.

    I have pictures of the chick and if you would like to see them I could email them to you. I would post them but I'm afraid they might bother some people who are not used to seeing these type of anomalies.

    How weird and unusual. It sounds like a set of not completly separated (conjoint) twins. "Siamese twins" Did it have two hearts? I am a pathologist and have done autopsies on babies with complex congenital malformations. I wish I could have seen your little chick!

    It was just a genetic anomaly...it can happen in any species, us included.
