I need to pick albumen and yolk from a 10-days-old chicken egg.
But I'm not sure about what I know about chicken embryo and some search results are not consistent
I think that number 1 in picture is amniotic fluid, number 2 is thin albumen, 3 is yolk, 4 is thick albumen and 5 is allantoic fluid.
please tell me if there is any wrong in my understanding.
