White dot on my chicken's head

[carrottoes]

It's very recent, but my RIR Rosie has a white dot on either side of her head. Here's some pictures:



It's just above her eye and below her comb



And here's her other side


They seem to get bigger everyday, but Rosie seems fine. Is this something to worry about?

Is it her feathers or is there a bump forming?
