We have a black sex link that lays eggs now that end up with a hole in it the size of the writing pen, one egg had
a thin piece of shell hanging from the hole, today's egg had a nice size hole letting the white run out.
She is going on three this coming fall. She had been laying eggs without any problem, now this season is different.
She is getting oyster shell, grit, layer feed, worms, bugs. All hens have free range of the yard. the shell at the hole is soft. Help please.

Does it look like she pecked it and ate it?? It looks like glitch eggs if not. Probably from old age.

No, it does not look like she peeked it or ate at the shell nor does it look like any of the other hens got at the egg. She laid the egg in a nesting box while all the other hens
are out in the rain.

Is the shell soft or hard?? It might be time to cull he off. Those eggs can break inside a hen and cause lots of problems.

I'll bet the shell around that hole is thin...incomplete shelling.
She's old for a sexlink, could be coming to the end of her laying years.
Like new layers, older layer going into/coming out of molt and at the end of their productivity can produce some funky eggs.

I see this abnormality in layers that are getting on in years. The shell gland fails to completely encapsulate the egg as it passes through. Calcium uptake may or may not be the problem, but aging almost surely is. These hens are signalling imminent retirement.
