I have one Leghorn in my flock that has been laying for about a month now. However, she has had some issues with laying consistent eggs. I have had many soft eggs that are broken by the time I get out to the coop. Usually a day of soft shell , then a day of small but good hard shell, then maybe another softie then a double yoker. I have also seen two soft eggs that seem connected somewhat on the same day. I have all brown egg layers except this one Leghorn so I am positive its just the one hen. I feed good layer pellet that includes oyster shell, I also supplement with a second select of oyster shell. They get plenty of protein, fruits and veggie but their main staple is the layer feed. All hens are happy, healthy and doing well. The other layers give consistent fully formed and hardened egg shelled eggs. I can't figure this girl out. She is young - just 6 months old. So, I understand that in the beginning there are some issues, but I've done my best to help regulate to no avail. Any help would be appreciated.
