It varies per chicken. if a chicken doesn't get enough calcium in their diet they can actually lay shells so soft they fall apart in their bodies. While others may be very hard. Even the same chicken can have different strength of shells if their diet changes. Some chicken owners feed chickens crushed oyster shells to get hard shells due to the calcium content. my chickens I share my yard with prefer real food with calcium in it. that said, they are all easily broken either way
