Rough, thin egg shells

Hi Everyone,

I've just past my first year with my flock of 5. Everyone is healthy except one. She has been laying eggs that have a rough, sandpaper-like texture and the shells are very thin. I feed oyster & egg shell free choice so unless she isn't eating calcium, she should be getting enough. Her laying frequency isn't a problem but if it is a calcium issue, then I worry about her getting egg bound.

I've noticed some sporatic sneezing from her. I have some Vet Rx and am going to start medicating the flock in the event there's some sort of respiratory issue. The only other thing that I notice with her is that her upper beak is slightly over grown and it's misshapen like she's been rubbing it on something that has caused it to be bumpy. She's eating fine and socializing fine otherwise.

I pulled out my Chicken Health Handbook by Gail Damerow and the only thing that I can find and that close in symptoms is a rare disease called Egg Drop Syndrome which I would find very unlikely because she's had zero exposure to water fowl.

Any ideas? If she isn't eating calcium would I be seeing these egg abnormalities? The rough shell has to be a stand out for something, I just cannot find it in the book that I have.

Thanks in advance!
 
Welcome to BYC.
What age is your bird and what exactly do you feed her?
She is between 10-12 months old. We feed Purina Layer feed and have Oyster shells mixed in (we added the oyster shells when this started). Her eggs have been perfect since we got her at the beginning of February. This started about 3 weeks ago. The shells seem to be very fragile and rough. You wouldn’t notice the roughness to just look at it, but when you hold it, it feels like a fine grain sandpaper.
 
Don’t mix the oyster shell with food. Put it in a separate pan available to the layers ro take when they need it. Sometimes calcium is not the issue, but you could give the hen some human calcium tablets with D 3 1/2 tablet daily, or a 1/2 Tums daily for a few days to see if it makes a difference. If not, the problem is probably her shell gland.
