and today I got 3 softshell eggs! I only have five chickens, so this is a big problem. 2 other eggs were hard, but one was broken. What can I do if they won't eat their oystershell? They have a small trough for their grit and shell, and I also mix it into their crumbles once a week, but it doesn't look like they eat it at all. Is there something else I can give them?
