Smart Feeder - Light sensor values

[Jewels]

Hi,

I am posting on behalf of my friend who has two chickens and one of them has been breaking the laid eggs. He has tried the trick of blowing an egg and filling it with mustard for a few weeks and still one of them is breaking the eggs. Could it be something lacking in their diet, or is it just a bad habit one of them has got into??

Probably just bad habit. I've got one who is always inspecting the nest box for thin shelled eggs She could try putting a pot egg in and hope it frustrates her
