Help with sudden behavior change

[Bigloretta]

My hens within the past couple of weeks have started scratching the hay out of their nest boxes, and pecking at their eggs. What could cause be?

Mites? Low protein?

 

[SilverBirds]

Are they EATING the eggs?

 

[Bigloretta]

Mites? Low protein?

No mites 22% protein

 

[Bigloretta]

Are they EATING the eggs?

No; just pecking small indentations

 

[SilverBirds]

Sometimes they like to fluff up the hay before laying. Or they may just be bored.
