Chicken eggs do not contain amniotic fluid like mammalian eggs. Instead, the developing embryo is surrounded by a fluid-filled sac called the amnion, which provides a protective environment. This fluid serves a similar purpose to amniotic fluid in mammals, cushioning the embryo and allowing for movement during development. However, the overall structure and composition differ from that of mammalian amniotic fluid.

Human eggs
Lions do not lay eggs; they are mammals, and like all mammals, they give birth to live young. Mammals have amniotic eggs in their evolutionary history, but they do not produce eggs in the same way that reptiles or birds do. Instead, lion embryos develop within the mother's uterus, surrounded by amniotic fluid.
Currassows are one of the three major groups of birds known as cracids. Most of these birds live in South America. Amniotes are eggs that contain amniotic fluid in them. Currassow eggs do contain amniotic fluid, therefore currassows are amniotes.
No. An amniotic egg will normally have multiple parts, like a chicken egg. An aminiotic egg also is surrounded by amniotic fluid. A fish egg is a small embryo surrounded by a protective gel like substance that is similar to a shell.

Eggs laid by mammals, birds and reptiles. They have a membrane that contains fluid. There is amniotic fluid around the embryo. It also has a protective shell that provides air to pass through.
An amniotic fluid embolism is a complication of pregnancy characterized by movement of amniotic fluid past the placenta.
Amniotic fluid is a nourishing fluid found in the amniotic sac of the embryo. Its main function is nourishment of the embryo. Please refer to the related questions for detailed information on Amniotic fluid.
Mammals, birds, and reptiles lay amniotic eggs, so, yes, owls have amniotic eggs. Amniotic eggs contain a yolk and aid in gas and energy exchange.
