    Okay so I have to answer this question for biology class, but I really don't know the answer so here goes:
    "why are human eggs so much smaller than chicken eggs?"

    I'm sure the answer is obvious but I can't seem to figure it out. Please help, thanks

    What are some of the other differences between human development and chick development?

    That may get you started.

    If only comparing the DNA contained in both eggs, they are almost the same. The chiken egg is independently developed outside the mother chiken body, so it needs great deal of nutritional materials in the last stage of development process. The human egg can absorb the nutrition directly from the placenta after it finished primary stage of development and embedded into the inner uterus wall.

    it's a trick question.

    They aren't.

    They just grow bigger. Can you imagine a chicken walking around with a life supply of eggs inside here?

    You can tell your teacher he is full of shit. And that he didn't think his question through.

    :lol

    Edit - just to say my lol wasnt so much at the teacher asking or not asking a trick question, but rather at the thought of t2me4tix telling his teacher he is full of shit.

    Feel free to correct any false information, which unknown to me, may be included in my posts. (also - let this be a disclaimer)

    maybe it's not quite the trick question that you think it is - if you compare the size of the freshly implanted human egg in the womb with that of a freshly laid chicken egg, there clearly is a difference in size

    the reason for this is that most of the chicken egg is really food stuff to turn the (far smaller) embryo into a chick
    as you well know human embryos are fed continuously through the placenta, hence don't need to carry a lifetime's supply of building materials with them

    And taking on from that - when is the comparison valid?

    1. At time of leaving the mother's body, the human is much larger than the fowl.

    2. At time of fertilisation, as far as I am aware, they're about the same size - isn't it after that the rest of the egg mechanism develops around the chicken egg?

    3. If its over the period of gestation then, as in 1 above, the human egg is bigger.

    So really, when, and in what way that isn't artifically contrived, is the chicken egg bigger than the human?
