    I have read several times on here that if you put some ground oyster shells in the feed, it will help the hens produce a better shell on the eggs they lay. My question is this; will ground fresh water muscle shells provide the same advantage or similar results? My son has been bringing these shells home every time we swim at the lake near our house. The bank is littered with them. Is this a good freebee?

    Yes, bivalve calcium carbonate is all pretty much the same [​IMG]

    ...as long as you're not concerned about the possibility of contaminants (e.g. heavy metals) built up in the mussel shells. There is of course no absolute guarantee of what's in the feedstore oystershell either, but if your mussels are within a couple hundred miles downstream of a WHOLE lotta agricultural runoff or something scary going into the water, you might think about it. I know zebra mussels in the great lakes have considerable heavy-metal contamination in their flesh (dunno about the shell, but given that heavy metals sometimes behave similar to calcium in the body, I would think it *possible*).

    Have fun,

    I agree with patandchickens.... I would be worried about contaminants.

    We don't put the oyster shell IN the feed. We put it in a separate area. That way the roo isn't wasting a bunch of feed trying to avoid the oyster shell and the ladies only eat what they need. So there is less waste on the oyster shell too.

    50# of oyster shell is pretty reasonable, I think I paid like $5-$6 for mine and even with 34 birds, it seems it will last a longggggg time. I'd feel better spending the money than risking a contaminate that may get passed into my eggs.

    Just my 2 cents.
