    I'm new at this so please bare with me-

    We have 2 hens that we're treating (naturally) for vent gleet. One of them laid an egg this morning and there's a huge white spot on the yolk.

    Can someone please tell me what it is?

    Just wanting to make sure that we don't have to treat for something else now. =-/

    Thanks in advance,

    don't worry! it's called a blastodisc, or if they egg has been fertilized a blastoderm. it's where a chick would develop if you incubated the egg.
