I’ve recently introduced crushed oyster shell into my 20 week old chickens’ diet. I keep hens with roosters, so I switched over to an all-flock feed a couple of weeks ago. Without any extra calcium supplement, like in layer feed, I thought that this would work for me. BUT then I started reading about how lead accumulates in oyster shells and then that led me down a wormhole of how lead is very frequently found in backyard flocks often attributable to contaminated soil. So now I’m paranoid to feed any eggs that I may get to my kids. My house was built in the 90’s, so I’m not convinced that my soil would be contaminated, but how about the oyster shell. Is there something available that I wouldn’t have to worry about lead? I know about crushed egg shells from your own flock, but I’ve read that it is common to quickly run out. Are there any other practical calcium sources for chickens?
