1 year old quit laying

[buddy18]

Our 1 year old black sex-link quit laying. The other 2 are laying everyday. She goes into the nest everyday to lay, but nothing. She also was laying some very small eggs, no yoke. She's not egg bound or she would be dead by now. They had mites a couple of months ago but we treated them for that. Her bottom is missing some feathers but other than that she's healthy. Is there anything I can do or she is done laying?

Is she broody? Sick? Acting normal?
Maybe she is taking a break or recovering from the mites.
