Small, yolkless eggs

[FarmerEz]

My four chickens are three years old - and someone has started laying miniature eggs with no yolks! See photos below. (Egg on the left is normal. Also how do you like my skelter?)

Have others experienced this? Is it just due to age?

Ya, get them occasionally also. People call them various things, wind/fart/rooster eggs are usually just a glitch in the egg laying system when a small piece of reproductive tissue breaks away (like the nice picture of the one you have) and is treated it like a yolk and a shell is formed around it. They are pretty common in old birds, brand new layers or birds just stopping or starting a laying cycle, sometimes they just seem to show up randomly. The occasional one usually isn't anything to worry about, if you get a hen laying a lot of them, especially an older bird, it may be signaling the end of her egg laying.
Very nice skelter, did you make it your self?

Thanks! It does seem to be a pattern, but since I have no idea which eggs come from whom, I don't know whether someone has just started to lay only these.

The skelter comes from here:
