Our hen laid 2 x 1/2 eggs...

[Zud]

Our Barred Plymouth Rock, Jane Aust-Hen, is 19 weeks and started laying this week. This afternoon she was unusually lethargic. Finally she climbed into a nesting box and laid an egg with a very thin shell, and part of the shell missing.
She kept moping around until she finally laid "the other half", which has a second yolk.
After a while she finally perked up and was back to normal. We're chalking the lethargy up to begin tired from the double lay... We fed her some limestone in sour cream to make sure she's getting enough calcium.
Is there anything that comes to mind that might be an issue to watch out for?
I attached a photo of her egg(s). That's how they laned.

Thanks!

That's very unusual.
Oyster shell or calcium citrate is much more effective than lime stone.

Walmart is just one example of where to get calcium citrate pills. I’m sure you have other stores with a vitamin section. Citracal is one brand name and most stores also sell a generic. Just make sure it has +D3 in it.

I agree that it might be good to give her some calcium citrate +D3 for at least a few days. You can get it in the vitamin section at Walmart or most pharmacies. I have seen @azygous recommend one pill a day. You can just pop it in her beak and she will swallow it.

and this thin shelled one just spit. lt's just that the split was so precise that had us baffled.

It looks like the shell split inside and was 'repaired' with further shelling.

We did some limestone in sour cream and those oyster shells ..

Not sure that will do it....the D3 is important for calcium absorption.
Tho the whole thing may just be a new layer glitch.

I’m sure you have other stores with a vitamin section.

Any store(grocery/drugstore) with a decent vitamin/supplement section should have the product type that @azygous posted.

Novice here so no good advice, but:

1. The "Aust-hen" thing is just genius, bravo, and

2. I've never seen an egg (or eggs) anything like that!

Following so I can learn from the replies. All I'd know to do is watch her closely to ensure she perks up and isn't feeling additional ill effects as the next egg rolls down the assembly line.

Wow! A hen that lays half eggs! Now, what a marvel it would be if she produced them already soft boiled! Now that would be worth phoning up the Guiness people to get her in the book.

Okay, sorry, it's been a long day in the hot sun. Seriously, I would do as @TX Chick Noob suggested, give her a calcium citrate tablet each day until she's kicking out one normal egg at a time. She's darned lucky she didn't break those yolks inside her trying to expel them. She'd be looking at a reproductive infection from bacteria growing in the yolk in her oviduct.

I recommend the citrate form of calcium because it's most easily digested and quickly absorbed, what we need in a reproductive crisis. This is what to get. One tablet per day directly in her beak. She will swallow it easily.

So... We took her to the vet today and she's got a number of undeveloped eggs backed up... Pumping in suppliments. Hopefully she starts passing them safely.

Did they do an xray?
Where are the eggs?

X2 btw those eggs look super cool but not normal definitely hope someone else willknow

I've had hens that were releasing two yolks per cycle and the calcium citrate remedied that, so they were then just releasing one per cycle. I don't know how the calcium therapy achieved that, only that it seemed to work.

The 660mg calcium citrate is powerful enough you shouldn't need to push the other forms of calcium. Again, this form of calcium is easier on a chicken's digestive system than calcium carbonate in such large amounts. It's much easier to administer, too. Just pop a pill into her beak once a day and you're done.

Once she's laying a proper egg, she can then go to oyster shell on demand for her calcium needs. The calcium citrate therapy is strictly short term as too much calcium over a longer period can harm the kidneys.
