Question

Do hens have internal fertilization or external fertilization

Answer 1

Internal Fertilization. ... In oviparity, fertilized eggs are laid outside the female's body and develop there, receiving nourishment from the yolk that is a part of the egg. This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds.

Answer 2

Hens have internal fertilisation. i.e fusion of male and female gamete takes place in the body of the female.
