We think that Jasmine has started laying. We're not quite sure, as we haven't had a full house day, but some days the brown egg in the next box is one particular shape, another day it's a different shape. We were expecting her eggs to be really really really brown, like mahogany, and these aren't.
I asked a friend of mine, who bought a Welsummer from the same place at more or less the same time as me, whether her girl had come into lay. She has, and her eggs are the same as the ones we think are from Jasmine.
So, we just need to see if they get darker. Hope so!
