Super weird textured egg?

[FernbergFarms]

hi, I got this really weird textured duck egg today from my Pekin hen. Should I be concerned about anything with her or is this normal? It looks a bit thin but I can’t tell for sure until I crack it

Is this the first egg like this you've gotten?
Do you have some kind of calcium supplement for them?
If it's not a recurring thing I wouldn't be worried at this point. Sometimes things just get wonky.

Just wanted to jump on here and say that one of my girls lays weird textured eggs too so you are not alone!! She's never laid a normal one and is a little over a year old. I always just thought it was too much calcium in her diet but the same duck recently started eating her eggs and the eggs are thinner so I agree with Isadora that the texture thing is likely a calcium deficiency. I am going to try giving my duck some calcium gluconate (orally) and extra eggshell. I'll let you know if there is any progress!

Do you feed your pekin layer feed or normal feed? And what's the oyster shell situation?

Also, here's a good resource:

My duck has a few minor birth defects from humidity problem when she was a wee little egg, so she may have defective shell glands and therefore her weird shells may be due to a different problem than your pekin!

And finally check out the second post on this thread: https://www.backyardchickens.com/threads/calcium-deposits.1500052/
their bird has laid eggs like that for 3 years and is fine! So don't worry, your duck is most likely fine!

Yesterday her egg had like 2 spots of weird texture but today it was the whole egg. I don’t have them on extra calcium at the moment And I feed them layer feed. Should I try giving her eggshell would that help/ just be good for her? We would always have grit for our chickens but I never really gave it to our ducks.

Grit is not a source for calcium, it's just used to help them digest their food.
For calcium you want to use oyster shells or crushed up egg shells.
I have a terracotta flower pot in my duck pen that sits near their food trough that has oyster shell in it. I see my duck hens take nibbles out of it occasionally.

Update:
So I’ve been giving them crushes eggs shells and she hasn’t laid an egg since the weird egg.. when I cracked the egg it was super thin like the shell was just falling apart because it was soo thin and usually the duck egg shells are super thick and harder to crack than the chicken eggs.
