I don't think it is a big deal...these things just happen from time to tiem.....they just slow down...they don't actually shut down..

I am reluctant to say that the chicken is shutting down. From my experience, the eggs are probably from the same hen. A hen is capable of laying an egg every 23 hours, if she does for a long period of time her oviduct will become too relaxed and the eggs get too close together resulting in malformed shapes and shellless eggs.

Willy, this weekend I got two eggs that had paper thin shells. One of the hens had layed a huge beautiful double yoker the day before. From what folks have told me this does happen from time to time and it's nothing to worry about. I did fill up the oyster shell dish though....I have a hard time keeping that bowl clean, not sure if it's related or just a flukey thing that happens from time to time.

Try giving them grit that helps the eggs.You can get it where you get feed

I get weird eggs from time to time, too -- once I had an egg that had NO SHELL at all, just a weird membrane. I've had really long oval eggs (totally abnormal shape), as well as eggs like what you describe-- whorls, and sometimes extremely grainy. These are all from chickens that otherwise just lay regular old eggs and about once every four months or so, they lay something weird.

I am curious about the double yolks because I actually just yesterday had my very first double-yolker in FIVE YEARS of egg-gathering. Do certain chickens lay more double-yolkers than others? Like twins run in families- certain hens are prone to double yolks?

Also do you feed egg laying mash or pellets?

Once in a while Ill get a weird egg. Something they'll be almost normal, but have a thin spot or a whorl like you mentioned. Sometimes theyre speckled. I have one hen that lays giant eggs from time to time. These sort of things happen year round tho--side note my hens dont really slow down during the winter.(and I dont use artificial light)

Kristen, my chickens have only been laying a little less than 4 weeks and I've gotten 4 double yokers so far :)

I was getting daily one egg that was larger, lighter in colour, and wrinkled like a prune. Upon cracking it there were bubbles (froth) with the egg. It may have been a little runny also.
This happened for the last 2-3 months, didn't know who was doing the laying. Anyways last weekend one rhode island red dropped dead off the roost and since then no weird eggs. Didn't notice any illness, but either way problem is solved.

I've had all that was mentioned above but only with very young hens when they first start to lay. After a while things seem to iron out. This year one of my easter egger's first eggs was a triple yolker! Had lots of doubles too the first few weeks of laying.

I wouldn't mind seeing a tripple yolker!
My wrinkle egg is back, darn it.

When my hens started laying I quite a few double yolkers....havent gotten any in a while....
