Chicken not laying eggs

[pvchicken1]

My sapphire gem has not been laying for the past 5 days. She usually lays 5-6 eggs a week. 2 weeks ago she was acting lethargic and didn’t want to eat or move. I watched her and suddenly he pooped out a egg white substance and the other chickens immediately started to eat it. A few hours later she was back normal. After 2 days she she went back to her laying routine. Then about 10 days later it happened again and she hasn’t laid anymore eggs. The day Before this happened again she laid an egg that was 2.76 oz.

She has acted normal since then and still hasn’t laid any more of her X-L eggs.

Hard to know if this is just a glitch or the start of an ongoing reproductive issue.
See that she's eating a nutritionally balanced poultry feed, has oyster shell available, limit treats.

She is on the producers pride feed from tractor supply. She has not laid an egg today but hopefully will soon. I will try to start her on some oyster shells and will cut there treats in half.
