Anyone else noticed this?

[Artichoke Lover]

I’ve noticed that my flock lays lighter eggs in really hot weather and darker eggs in the cold. The eggs on the right were collected about two weeks ago when the weather was mild and the ones on the left are from today after the weather has been in the 90s for over a week. Not concerned just find it kind of interesting

Never really noticed it in relation to temps, but coating density can vary.
