I eat eggs sometimes, but I'm not proud of it. The moral considerations are very different from oysters because of how they're produced. Producing a lot of eggs requires a lot of hens. Having a lot of hens (and not roosters) involves killing a lot of male chicks. Producing any volume of eggs economically requires having a lot of hens in not that much space, which typically involves things like clipping beaks. This also produces a lot of concentrated waste which can often cause environmental damage. Keeping a lot of hens fed requires that you give them a lot of feed, which requires agricultural resources which might otherwise have produced food to be eaten by people. So eating eggs entails killing and torturing birds, producing toxic waste and using agricultural resources inefficiently.
