Weird eggs

[Saxophonetiff]

One of my Golden Comets has been laying weird eggs. Progression from light tan to cream to off white to white. With each shade lighter the egg becomes thinner and more calcium deposits.
They eat a pellet with oyster shells and get larva treats occasionally.
The egg I got today was so thin my finger nail cracked it just by collecting it and you can see through it when help up to the light.
Any ideas?

Have you actually seen her eating the oyster shell?

How old is it?

She might be in need of some calcium+Vit D3+Vit. K, there are additive for their drinking water or just use the tablets for human consumption.

Do they have access to granite grit to properly process the oyster shells?

Yes, my pellet feed has it mixed in.

She is around 1.5 years.

Thanks for the advice! I will look into this. Yes, they have my access to grit. All my other girls of the same age don’t have any issue it seems.

Sounds like she a picky eater. Usually if there on layer pellets they don't require oyster shells. My hens don't seem to be using my oyster shells at all. They do like the smashed eggshells I throw in my compost and the pellets. Although I do give them a lot of vegetable greens, some contain calcium also and other minerals. I never had any problems with egg shell density.

Best to offer oyster shell on the side so birds that don't need extra don't ingest it.

For the problem bird, might try artificially boosting the calcium intake for a couple weeks to see if that makes a difference. Some folks on here swear by calcium citrate tablets (the ones made for humans) as that type of calcium is more readily absorbed.

Thank you for your suggestion! I will add I feed them black solider fly larva(which is supposed to be highest calcium larva?) as treats and make sure I feed to each one. I just have assumed they are all getting enough. Since there were calcium deposits I also figure they were getting enough.
