Real oyster shells and crab shells from xmas dinner--can I use these?

[firsthouse_mp]

My husband saved all the oyster shells and the body shells from the crabs that we ate for Christmas dinner. I have three dozen oyster shells and 6 crab shells. If I put the oysters in a fabric bag and send my 9 year old little guy out with a hammer, do you think my hens will eat this crushed shell??

This sounds like I could be both "recycling" and creating a FUN project for my son (a hammer is a boy's best friend right?)

What about the crab shells...anyone ever fed those to a hen?

I don't see why not as long as they have been heated enough to destroy any bacteria that might be present.

I would absolutely do just that, with both the oyster shell and crab shell.

I'd put that crab shell in a strong blender with a little water to keep things moving. Just long enough for bite sized pieces, then strain. In fact I will from now on, thanks for the idea!

Oh good! I do like the hint to try and sterilize them too--maybe I will put them in a quick dip of boiling water for 5 min. Thanks everyone!

I crush up quahog (it's a clam) shells on the patio with a hammer and they eat the little pieces when they are out in the yard. I do give em a quick scrub with a brush in the sink to get any xtra salt off.
