Bird eggs range from the size of shot puts (ostrich eggs) to smaller than aspirin tablets (hummingbird eggs). Not all birds lay the “egg-shaped” eggs of a chicken. Owl eggs can be round as golf balls. Hummingbird and swift eggs tend to be shaped more like a capsule, long and narrow. Shorebirds and birds that nest on cliffs often lay eggs pointed on one end and rounded on the other, a teardrop shape when viewed from above. Some biologists think this shape allows the mother bird to cover eggs more efficiently when the pointed ends face inward, making the eggs fit together snugly. The shape also makes the eggs roll in a circle, which may be an advantage to birds nesting on flat, narrow ledges.

Hi there. As the hen pushes out the egg, the cloaca closes at the terminal end of the egg. The pressure exerted will make the terminal end of the egg smaller. Have a tweet Christmas.

When they pop out of the chicken or whatever that's laying them, the pointed end is the strongest so it protects the egg from breaking when it hits the ground. AN egg shape is physically strong and its strongest point is the pointed end!

so that when they roll, they roll in a circle. Very useful for eg, seagulls who lay their eggs on ledges on cliffs. If their eggs were round and they were nudged, they would just roll into the sea, whereas a pointed egg rolls round in a circle and stays on the ledge (most of the time!). Try it with a hens egg on a table (maybe!)

the reason eggs are pointed at one end is because that is where the air space is at for them to live inside the shell. during birthing and hatching process. it is always where the head ends up at.

It's yet another of Mother Nature's miracles. For easy "laying" and when the eggs harden the oval shape stops them from rolling away!

Two Reasons
1. If you roll an egg the shape means it rolls in a circle...this helps stop it rolling out of the nest
2. the shape is very strong particularly from pressure applied from above

eggs are shaped the way there are so they stay in the nest, this way the eggs have a higher survival rate.

so that when you drop them theyre less likely to break!!(try holding the tips of an egg between your fingers and no matter how hard you press the egg will not break!!!!!)
