Any ideas who's eating the eggs?

Perhaps a fox has got them from a rubbish sack after someone threw them out because they were out of date. Hate mysteries!

They look pecked by, perhaps by a magpie, rather than taken by a fox or other animal.

The seagulls round here peck the rubbish sacks - even though there is no food in the general waste there could be a piece of kitchen roll with a little food on it and they peck the sacks and strew the rubbish everywhere.
(We don't have bins here.)

Some animals can bite holes in eggs without smashing them - the polecat or weasel is the likeliest culprit, as it is hens' eggs we are talking about.

I had a cat once who fetched wood pigeons eggs out of their nests without breaking them. She brought them in to eat in comfort and made a neat hole in one end with her big teeth.

I feed a few Foxes and they love eggs, I put one out with their food every night. I'm not saying that is what is happening to the ones you are finding but it is possible, as someone else on here said, get a night camera, then you might see who is visiting.

Perhaps there is something more sinister going on. Perhaps the eggs have been poisoned?

I agree with Jane10 and Moggie57. Set up CCTV on several spots and see who's the culprit.

Perhaps the eggs have been poisoned?
Not quite the same thing, but one of our frequent food alarm warnings (in OZ) concerned salmonella in eggs.
Now I'm worried as to whether the chickens are the problem!?
We could save them up for our General Election next month!
