Answer 1

Internal fertilization:

1. Internal fertilization in chickens refers to the fusing of male and female gametes within the female body.
2. The fertilization takes place inside the hen's oviduct and occurs immediately following ovulation.
3. Soon after fertilization, the zygote divides repeatedly and travels down the oviduct.
4. As it travels down, many protective layers are formed around it and after the hard shell is formed around the developing embryo, the hen finally lays the egg.

Final answer: In hens, fertilization takes place inside the body.
