Is it possible/likely that a hen would lay ONLY male eggs?

    Someone told my husband that eggs
    that are sort of "pointy" on one end are
    male eggs...

    eggs that are more rounded are females...

    anyone ever heard that? Any truth to it?

    And, if it is true, I have two NH Red hens
    that lay ONLY male eggs...

    there are two hens and a very beautiful
    roo....the roo favours one hen only...

    I told my husband that the hen that's
    getting "laid" wants a new, she's
    laying only roo eggs so she'll get a new

    and, the lady that's not getting ANY, wants
    a roo for herself so SHE is only laying
    roo eggs!!! :)

    Both of their eggs are always long and pointy...

    and, I have a whole lot of roos in my flock...

    I've NEVER hatched a female NH Red - ONLY

    would love to hear some stories

    Old wives tales. But, old tales are often based on some element of truth. The reality is that the sex is determined by the hen, not the rooster. Mammals are reversed, where the male determines the sex.

    It has been shown that some hens do indeed lay a propensity, almost an exclusively, one sex. That much seems documented. Unless you trap nest and mark the eggs and hatch out a bunch of chicks and ankle or wing band those chicks and kept scrupulous records, it would be very, very difficult to establish which hen was doing what.

    As for the shape thing, I've heard that many times before. Seems like the hatcheries would simply employ that method, right? Not!!!! Millions and millions of dollars are spent in research on these matters in the table egg industry.

    But, someone probably read it on the internet and we know that everything on the internet is true. [​IMG]

    That's not at all true. The female has genetically predetermined how many female and male offsprings when the eggs are fertilized. Female chromosome is in charge in this situation.

    Thank you all very much for your
    responses :)

    I seem to hatch a ginormous
    number of roos and extremely
    few hens...

    that's from NH Reds, Red and
    Black Sex Links and combinations

    of all.....

    People do not seem to want roos...
    and I have so many of them...

    The thought of them ending up
    on someone's dinner plate is sad...

    what do you all do with your "extra"

    Thanks a bunch

    Of COURSE everything online is true :) NOT!!!

    It sort of made sense to me, though....

    I was hatching roos, almost exclusively ....

    I'd read that you should put the "large"
    end of the egg up when incubating them
    or the chick would be very disoriented
    when it hatched???

    so, it was much easier to see the "large
    end" on an egg that was somewhat
    pointed on one end...

    A family of raccoons broke into the
    chicken run and killed 35+ of my new
    babies... 5 remained - and 4 of them

    seem to be roos ;(
