    The Lash Egg.
    Or, what the hell just came out of my chicken?

    There is no end to the gross oddities that you're exposed to when you have chickens. Chicken keeping is not for the faint of heart. Or fainters in general. Partly because of the lash egg.

    Now I'm not a farmer. I'm a regular gal in a regular house with nice shoes, an affinity for gold plated flatware and expensive haircuts. I also have chickens. So my shoes get chicken crap on them and I once left the grocery store realizing I had a piece of straw sticking out of my expensive haircut. That straw had chicken poop on it.

    So even though the chicken poop part of me could handle what I found in the nesting box the other day, the nice shoes part of me was aghast and disgusted.

    When you have chickens, most days things go without incident. It's just you and your gorgeous chickens as they romp in the straw, scratch in the dirt and dance in the sunshine (everything seen through a filtered lens in slow motion). No, seriously, they dance in the sunshine. For real. Then one day you go to the chicken coop and you find something new. Something unusual. Something horrifyingly gross.

    Such was the case last Tuesday.

    Last Tuesday I went to check the nesting boxes, (where the chickens lay their eggs) like I normally do.

    nesting-box

     

    And I found an egg like I normally do.

    Only it wasn't an egg, it was a horrifying rubbery blob.

    I knew right away I had a problem. One of my chickens clearly needed an exorcism.  Barf.

    Double barf.

     

     

    The chicken owner part of me removed the offending rubber blob from the nesting box, but the gold flatware part of me refused to touch it.

     

    This, dear readers, is a regular egg sitting beside a lash egg.

     

    lash-egg-and-real-egg

     

    A lash egg isn't an egg at all, only it is.

    I asked poultry vet Dr. Mike Petrik, The Chicken Vet, what the hell this is and what causes it.

    This was our email exchange:

     

    Dear Mike,

     

    What the hell is this and do my chickens need an exorcism.  I have some sage around here somewhere and I think I can find a priest.

     

    Karen Bertelsen

     

    Dear Karen,

     

    This is the result of an egg partly forming, then getting "hung up" in the oviduct.  If you squint, you can imagine that the bigger piece is the yolk and the funny shaped part is a collapsed membrane that is folded around some amorphous material.  The membrane is the part where the shell would have formed and the amphorous stuff is the protein from the egg white, once the water is removed.  

    Would you like to save this stuff?

    We'll email you this post, so you can refer to it later.

    This often happens with sick chickens, since the first response to illness is to conserve resources.  The egg stops whereever it is in the process.  If you cut it open you can see the yolk is cooked.  The result of a fever.

    It is quite possible that this is from Cuddles and is a sign that she is fully recovered and ready to come back into production.

     

    Mike Petrik

     

    Okey doke.  So let's cut it open!

    I'm losing count here but I think we're up to triple barf.

    The inside of the disgusting lash egg.

     

    dissected-lash-egg

     

    And just as Mike predicted, some of it is cooked on the inside.

     

     

    parts-of-lash-egg

     

    Now let's cut each half in half again.

     

    lash-egg-gross

     

    Now you can really see the eggshell membrane in there.

     

     

     

    egg-shell-in-lash-egg

     

    So this was definitely an egg that was just about finished forming when something went awry.

    The morning after this happened, Cuddles was back in the nesting box but she didn't lay anything. In fact she hasn't laid anything since. But she seems to be happy and healthy.

    Other than that whole head spinning around incident yesterday.

    Meh.  I'm sure it was nothing.

      My Bertha RIR IS 2 YEARS OLD NOW. she laid a lash egg. Ugh my heartbroke. I decided to cut it open. Yes I had gloves on. Oddly enough there was no solid inside there were a couple layers looked onion peels,but it was liquid no smell the liquid was well hard to explain you know when you pop a zip and the solid icky comes out then it oozes that clear light pink liquid that's what this had. That was March 18th she has since laid a strand of egg shell and 1 extremely large soft egg. But nothing else. I constantly have to give her Epsom salt baths but they just aren't helping. What do I do? She is still spunky full of life eating like a champ drinking fine and poops like a champ also.

        Hi Brandi! If she were younger I *might* toss it up to youth, but those would be big mistakes even for a new layer. If the egg isn't solid, she probably doesn't have a fever, but the first thing I would do anyway is take her temperature. Then go from there. If she has a fever she probably needs antibiotics. If she doesn't have a fever then it may be a different anomaly. :/ So sorry! ~ karen!

      I have 4 chickens. This is the second time I found this horror. The first time there was two of them in the esting box. How do I know which chicken this is from and should I butcher them and start over?

        Hi Cheril. Finding out who laid the egg might be a case of watching them to either see them lay it, or to see which chicken might not be feeling well. If you use them for meat birds as well, you could cull the one that is laying the lash egg but do you want to eat it if that chicken is sick? ~ karen!

      Ugh, I found a lash egg in my nesting box yesterday…
      Broke my heart.
      As most everything I have researched… is saying the hen is sick.
      I don’t understand what has caused her to get sick,
      All four of my chickens seem to be acting fine, so I can’t really tell which one it came from..
      And is it something I have to worry about spreading to the others?
      Thank you.

      I want to show a picture of my lash egg only to be sure that is what it really is. It was nothing like anything cooked . More like an embryo sack with an umbilical type chord on it and The Whole thing was more like a deflated water balloon that was pierced and drained by accident as the others laid their daily eggs in the same nest .

        That's O.K. A lash egg can happen like that as well. It sounds like it was more of an anomaly rather than an indication the chicken is sick. If it were sick, it has a fever and that's what "cooks" the egg inside. ~ karen!

    My name is Karen Bertelsen and I was a television host. In Canada. Which means in terms of notoriety and wealth, I was somewhere on par with the manager of a Sunset Tan in Wisconsin.

    I quit television to start a blog with the goal that I could make my living through blogging and never have to host a television show again. And it’s worked out. I’m making a living blogging. If you’re curious, this is how I do that.

    So I’m doing this in reverse basically. I’m the only blogger who is trying to NOT get a TV show.
