Complete answer: The difference between hen’s egg and frog egg is given below

Hen’s egg	Frogs egg
1. The major difference between a hen’s egg and a frog egg is that the hen’s egg is amniotic.	1. Frog’s egg is not an amniotic egg.
2. Eggs of hen contain amniotic fluid.	2. But on the contrary frog eggs do not contain the amniotic fluid.
3. Hens are amniotes.	3. Frogs are anamniotes.

Additional information:
Amnion means the membrane which surrounds the foetus. Amniotes are the animals that contain the amnion filled with the amniotic fluid and are characterized to lay eggs on land. This is because the amniotic fluid is protective in nature. It acts as a cushion for the growing foetus but also conducts the pathway for the exchange of nutrients, water, and biochemical products between the mother and the foetus. Amniotes are animals which are characterized to lay eggs in water as they do not contain amniote. Hence the absence of amniotic fluid puts the egg in danger of getting desiccated. Therefore, amniotes lay their eggs in water. Fishes and amphibians belong to the amniote category.

Note: In humans the amniotic fluid is commonly called water. Amniotic fluid is generated from the maternal plasma. Amniocentesis is a procedure where the amniotic fluid is removed from the mother for the early diagnosis of a genetic disorder and to collect the genetic information. The baby's genetic health as well as the age and viability of the fetus can be known by the process of amniocentesis.
