What is wrong with my Red Sex-Link Eggs?

[aart]

Normal

Nothing on the inside of the shell where that "bloody spot" is?

They do free range 3 - 4x a week.

For the whole day or for a short duration? Only asking because it affects the issue below.

And what would be the appropriate space for these 10 hens...
Coop?
Run area?

Combined 140 sq ft if you go by recommended minimums on here, but I think in many cases the minimum isn't enough as it doesn't provide the extra space needed to add clutter and other enrichment items to keep birds busy and to provide hiding places in order to minimize bullying issues.

Normal yolk. Like I said tho, more often than not it gets broken. Thin shell but ESPECIALLY on that spot.

This is really sounding like a shelling gland defect in which case there's not really much you can do about the faulty shell. You mentioned direct supplementing calcium to her before, for how long, how often, and what type (i.e. calcium citrate tablets)?

Once daily for a week. Citrate, 600mg.
Is that common that she'd lay just fine up until now & then this?

Not common, but not unheard of either. Production birds are more prone to reproductive issues, and this is one of them.

Citrate, 600mg.

With Vit D3?

With Vit D3?

Yes.
I'm worried about egg eating now if nothing can be done to help her. Could another regimen of calcium be helpful or do more harm?
