Hello all. I have 18 week old pullets. They are my first and doing well. I know I am supposed to start giving them oyster shells and have purchased some. The problem is I am hesitating because the pieces seem so sharp. Even if I was to make them smaller I feel like I will be feeding them shards of glass! I know I fuss too much but I need to know if anyone has had a problem with oyster shells. I lost one of my girls earlier to a crop problem and now am a little nervous. Any advice will be appreciated. Thanks.
