I mentioned this a day or 2 ago. This happened to my chickens. Today on my local craigslist page I see another chicken owner saying they have a surplus of eggs from their chickens and are giving them away for free. I contacted the person to ask what kind of feed they're using. Haven't heard back yet.
This could be the result of some faulty vitamin/mineral ingredients going into the feed. I'm just speculating here. It is my understanding that some vitamin additives for foods in general come primarily from China. Another thing we have to fix.
