Chicken laying rotten eggs

[Katiec66]

Hello

I have a four year old hen who has started laying rotten eggs, the eggs are perfectly formed, the white and yolk all look normal but they smell awful. This particular hen had an impacted crop 3 years ago and had an operation to clear the crop, since then she hasn’t been a regular laying hen but when she did lay the eggs were always normal until recently. Her crop is a slightly larger than the other hens but then out of all of them she is the greediest and always seems to be eating, she’s bright in her self charging around with the rest of the flock. I’m not sure if the rotten eggs are an infection as a result of her crop, any ideas?

Thank you

What do the eggs smell like? Sulfurish?
Does birds breath/mouth smell bad too?
What all and how exactly do you feed?

I suppose you could say it's sulfurish, I haven't noticed a smell from the chickens breath.
They have Marriages Layer Pellets and as a treat Marriages mixed corn, sometimes spring greens and they have a chicking lickin nutri pecking block

Do they smell fishy at all?

I found this article that was interesting:

I have recently come across 2 rotten, smelly eggs, both times from the same older hen, 6 years old and for some reason laying quite a lot this year. I'm unsure how old the eggs are - I'll check some of her newer eggs tomorrow - but they shouldn't be so old as to have gone rotten - I think there's a problem with the hen. She has been having poopy butt problems - I cleaned her up and she got it again the next day, drippy white. She has typically had a bit of a loose muscle so her eggs will often come out with a spot of poop.

There are several forum posts about people finding rotten-smelling eggs, sometimes with black or green yolks. Nobody on the forums seems to have confirmed causes of these situations, but it looks possible that it is a bacterial infection of the reproductive system, something that might possibly be able to be treated with antibiotics. Unfortunately often the people on this forum who post about this situation are new people, who don't reply back about solutions/how the situation resolved or didn't; and others often tell them they are old eggs. Not necessarily so - this can be a rare but major chicken health problem, it seems.
