Egg shell color and texture

[Jayywhat]

My opinion is that calcium warts are not going to sicken and kill your hen while withholding oyster shell could cause a deficiency that could endanger your hen's heart among other important things. It's best not to monkey around with this. It may be a temporary thing and in a few weeks, it will be past.

Thank you

I wouldn't withhold calcium.
Eggs are white and "color" is applied while in the shell gland. Sometimes as a season progresses shell color can lighten.
Have you had any changes to your flock recently? Any stress?
Probably a glitch and will resolve on it's own, but you can always check her over for lice/mites and get a fecal float to see if worms may be part be an issue as well.

It’s true, it is better than thin shells. I could just be paranoid since I lost one hen this past summer and another one this past winter.

Oh, I'm so sorry.

I have two Bielefelders and each lays a different shade of brown egg. I figured their genetics just lined up differently. They are both 9 months old. The calcium deposits...don't know but better than thin shells? Attached is a picture of my girls' eggs.

Pretty eggs
