Thin shelled eggs

[OhioChickToo]

We've been feeding Layena crumbles and now have switched to Layena Pellets. Oyster shell is always available and the girls are all free range--outside with access to the entire yard all day until they are ready to roost. Eggs have been great but we've been having a heat wave. Not surprisingly the egg production is waaaaaaaaaaaaaay down, but the eggs from 2 of our girls are slightly sandy/ chalky and thin. Any suggestions or is this just something which happens?

My chickens have been laying thinner-shelled eggs lately. I think it's because they ran out of oyster shell and I didn't replace it like I should have. Bad me. When they have free-choice oyster shell, their eggs are hard to crack open. Mine get Layena pellets also, and they free-range all day.

You said yours have oyster shell, so I don't know what is causing the thin shells.

Something you need to keep in mind is that you can feed all the extra calcium you want but if you don't bump the Vitamin D (D-3)
your chickens might not be processing the calcium. What you could do is start adding vitamins to there water.
With out the proper Vitamin D3 there calcium (Ca) and phosphorus (P) metabolism could be thrown off.
