So, I am concerned about one of my Easter Eggers. She is about 1.5 years old and was laying great with no problems until about 2 months ago. She started laying soft eggs or shell less eggs. I have been feeding the girls starter and grower feed due to the chicks that were hatched about about 4-5 months ago but have free oyster shell available. During our hot spell a few months back she was laying fine but then then all the sudden the soft shelled or shell less eggs. At first I thought it was just a fluke that happens once in a blue moon but this has been pretty consistent, almost every egg. She has laid a semi hard egg about 2-3 times but the majority have been soft. For the past two weeks at night I see her tail down and she does not forage or walk around with the girls after 6pmish. Instead she heads into the house and roosts. Then around 8pm to midnight she lays a soft egg. The next day, she goes into the nesting box and sits like she is going to lay and egg and after a few hours, comes off the nest and walks and runs around like everything is normal. For the past week, I have been giving her a bit of liquid calcium before she heads into the roost to see if it will help. This has been going on for months now and I am a little concerned and I know this can't be normal. She also has not started her molt yet. Any ideas on how I could help her?
