Are these oyster shells suitable for ducks?

I use the manna pro and have ever since I got chickens 5 yrs ago. My ducks nibble on it as well. The bag lasts quite a long time. I've never had any issues, but as with all things, inspect before giving it to your chickens or ducks.

I had the Manna stuff and had some bits of wool, I suspect some ended up in ducks, they seemed to suffer no ill effects. I picked out as best I could and got a whole different product next time.

Be careful with those. I found actual shards of steel wool on the one and only bag of Manna Pro's 50lb oyster shells I purchased. I'm not talking just one piece the bag was absolutely littered with pieces of metal. I don't know if it was a bad batch or what, but never again will I allow those oyster shells anywhere near my ducks.

will this brand work?

That's just crazy. I wonder if manna pro uses some sort of steel wool machine to clean the oyster shell? Did you reach out to the company?

Of course, almost any brand would work. Dumor is a tsc brand.

No, didn’t bother, @Isaac 0 said he had the same experience, pick them out and move on. I switched to this product and they seem to like it, more consistent size and smaller, I believe it is an stone product rather than ground shell. And actually I haven’t seen shelless eggs since switching now that I think about it.

This is definitely bothersome, but I have had the same bag since the beginning and have found nothing. But, next time I need some, I will look for another brand. I don't think I have many options though. Its tsc or a local feed mill. The feed mill has manna pro.

I now use either Small Pet Selects or Mile Four's oyster shells. I haven't had any problems with those brands. My ducks seem to prefer small pets, but when the oyster shell stocks got low they did eat the Mile Four's just fine. I think mile four's is actually an alternative to oyster shell with all of the shortages.

If you want to give your ducks calcium I recommend making your own, for my quail I take shells from chicken eggs (when I make am omelet or something), wash them, dry them out, then bake them on the lowest temp my oven can bake at for about 10-20 minutes and then grind the shells up. This calcium dust worked perfectly for my quails, I just mixed it in their food and they gave lots of good eggs. I'm not sure about ducks, I've never raised them to a laying age
