This is so interesting! Thank you for sharing this. I really hope I kept the bag and it states what's actually in the bag. I wonder if that's why I am having so many shell issues with my chickens? My Pekin Duck is having shell quality issues too but she's molting. I have given her calcium citrate + vitamin D3 on a few occasions but it doesn't really change much. I'm going to be looking into this. Thank you so much for bringing it to our attention! I think I'll look into buying some of the flakes either way. Thanks again for everythingFrom the vendor’ email to me:
We did testing on the clam and coral mixes that are out there. Chickens and ducks cannot absorb any calcium from them, they are very hard and just pass through their system.
