I used this for years and ducks ate it but not as much as they should have until i got flaked kind and now they have no more soft shells so this is ok but not the best
Pros: Easy to use and mix in feed for proper calcium supplement. Good Price.
Cons: I really do not have one.
I mix my oyster shell in my hens feed and have no problem with them eating it. This is the best price I could find on the market. I just store in a feed vault. Works great!
