Tiny Egg?

[cnielsen]

We have 6 laying hens, one of which is a bantam. we have another hen who we were told had already stopped laying by the time we got her.
recently i’ve been seeing the old hen sitting in the nesting boxes, and we have been finding these extra tiny brown eggs! could she be laying some glitch eggs? she’s about six/seven years old.
top is the small egg, middle is the bantam egg, and bottom is a normal sized egg.

It may very well be her or it may be another bird getting ready to take a break in her laying cycle.
