Misshapen Eggs: Round, Torpedo, and Flat-Sided Shells Explained
Odd-shaped eggs are common and usually harmless. New layers produce round, tiny, or torpedo eggs while their systems calibrate. Flat-sided eggs typically mean two eggs met in the shell gland. Persistent extreme shapes from an established hen, especially with production loss, are the version worth looking into.
Most likely causes
- New layer
Shape settles within four to eight weeks of the first egg.
- Double ovulation
Two eggs sharing the shell gland flatten each other's sides.
- Crowding and stress
Rushed laying and interrupted nesting deform eggs.
- Age
Very old hens lay more irregular eggs as the tract loses tone.
What to do this week
- Wait it out for pullets in their first two months of lay.
- Add nest boxes and reduce crowding if several hens are affected.
- Keep a simple log of shape by hen so trends are visible.
When it is worth a closer look
- A previously normal adult hen suddenly lays only deformed eggs.
- Deformed eggs plus lethargy, a hunched posture, or straining.

Common questions
Are misshapen eggs safe to eat?
Yes, if the shell is intact and clean. Shape alone does not affect edibility.
Why is my hen laying round eggs?
Round eggs are typical of pullets in their first weeks of lay and usually normalize on their own.
