Egg like a balloon
QOne of my pullets has just produced a weird membrane — it looks more like a balloon than an egg. All of my other hens and pullets are laying perfect eggs. Why did my pullet lay this ‘balloon’? Should I be worried?
AJulie Moore says: Your pullet has laid a shell-less egg — the shell membranes were placed on the yolk and egg white but somehow the shell was not deposited. As the shell forms just before an egg is laid, stress caused by fright or excitement can cause a hen to lay prematurely before the shell is complete.
Sometimes, a pullet coming into lay, particularly if she has matured early may lay shell-less eggs simply because her reproductive system isn’t fully developed. This is the likely explanation in your situation.
A diet deficient in calcium or vitamin D can also cause soft shells.
The occasional shell-less egg is nothing to worry about, but if they persist, it may be a sign of a disease such as infectious bronchitis or Newcastle disease which is something to worry about and an avian veterinarian should be consulted.
