After much research, I've concluded I don't have a clue what's going on. I've two light Sussex. They've finally got the hang of laying eggs. We seem to get two hard shelled eggs and nearly every day one soft shelled egg from these two. The hard eggs come about 24 hours apart, and the soft one can be laid anytime, from the afternoon to an hour before the hard ones are laid. What is going on? And how do I correct it. It's not calcium, food etc issue as fat as I can tell. Any advice appreciated.
