Question

how does the development of the hen's chick happen from a zygote?​

Answer 1

Answer:

heya mate✌

fertilisation takes place inside the body of the hen, the fertilised egg or zygote divides repeatedly to form embryo which travel down the oviduct. 2)As it travels down the oviduct, many protective layers are formed around the embryo. The hard shell that we see in a hen's egg is the outermost protective layer.....hope it hlps♥️
