Hi! When I collect eggs the some of the eggs are broken. Is it possible for the eggs to crack when they hit the nesting boxes? Or do the chickens peck at them? We had a problem pecking at them 2 months ago, but we fixed the problem by replacing the eggs with golf balls. What should you do if they breaking when hitting the nesting box? We have shavings in the nesting boxes. Any help would be awesome! Thanks!
